delivered the opinion of the Court.
At issue in this case is the constitutionality of the following Chicago ordinance:
“A person commits disorderly conduct when he knowingly:
“(i) Pickets or demonstrates on a public way within 150 feet of any primary or secondary school buildPage 93ing while the school is in session and one-half hour before the school is in session and one-half hour after the school session has been concluded, provided that this subsection does not prohibit the peaceful picketing of any school involved in a labor dispute . . . Municipal Code, c. 193-1 (i).
The suit was brought by Earl Mosley, a federal postal employee, who for seven months prior to the enactment of the ordinance had frequently picketed Jones Commercial High School in Chicago. During school hours and usually by himself, Mosley would walk the public sidewalk adjoining the school, carrying a sign that read: “Jones High School practices black discrimination. Jones High School has a black quota.” His lonely crusade was always peaceful, orderly, and quiet, and was conceded to be so by the city of Chicago.
On March 26, 1968, Chapter 193-1 (i) was passed, to become effective on April 5. Seeing a newspaper announcement of the new ordinance, Mosley contacted the Chicago Police Department to find out how the ordinance would affect him; he was told that, if his picketing continued, he would be arrested. On April 4, the day before the ordinance became effective, Mosley ended his picketing next to the school.1 Thereafter, he brought this action in the United States District Court for the Northern District of Illinois, seeking declaratory and injunctive relief, pursuant to 28 U. S. C.
After a hearing, the District Court granted a directed verdict dismissing the complaint. The Seventh Circuit reversed, holding that because the ordinance prohibited even peaceful picketing next to a school, it was overbroad and therefore “patently unconstitutional on its face.” 432 F. 2d 1256, 1259 (1970). We granted certiorari, 404 U. S. 821 (1971), to consider this case along with Grayned v. City of Rockford, post, p. 104, in which an almost identical ordinance was upheld by the Illinois Supreme Court, 46 Ill. 2d 492, 496, 263 N. E. 2d 866, 868 (1970). We affirm the judgment of the Seventh Circuit, although we decide this case on the ground not reached by that court. We hold that the ordinance is unconstitutional because it makes an impermissible distinction between labor picketing and other peaceful picketing.
I
The city of Chicago exempts peaceful labor picketing from its general prohibition on picketing next to a school.2 The question we consider here is whether this selective exclusion from a public place is permitted. Our answer is “No.”
Because Chicago treats some picketing differently from others, we analyze this ordinance in terms of the
The central problem with Chicago’s ordinance is that it describes permissible picketing in terms of its subject matter. Peaceful picketing on the subject of a school’s labor-management dispute is permitted, but all other peaceful picketing is prohibited. The operative distinction is the message on a picket sign. But, above all else, the First Amendment means that government has no power to restrict expression because of its message, its ideas, its subject matter, or its content. Cohen v. California, 403 U. S. 15, 24 (1971); Street v. New York, 394 U. S. 576 (1969); New York Times Co. v. Sullivan, 376 U. S. 254, 269-270 (1964), and cases cited; NAACP v. Button, 371 U. S. 415, 445 (1963); Wood v. Georgia, 370 U. S. 375, 388-389 (1962); Terminiello v. Chicago, 337 U. S. 1, 4 (1949); De Jonge v. Oregon, 299 U. S. 353, 365 (1937). To permit the continued building of our politics
Necessarily, then, under the Equal Protection Clause, not to mention the First Amendment itself, government may not grant the use of a forum to people whose views it finds acceptable, but deny use to those wishing to express less favored or more controversial views. And it may not select which issues are worth discussing or debating in public facilities. There is an “equality of status in the field of ideas,”4 and government must afford all points of view an equal opportunity to be heard. Once a forum is opened up to assembly or speaking by some groups, government may not prohibit others from assembling or speaking on the basis of what they intend to say. Selective exclusions from a public forum may not be based on content alone, and may not be justified by reference to content alone.
Guided by these principles, we have frequently condemned such discrimination among different users of the same medium for expression. In Niemotko v. Maryland, 340 U. S. 268 (1951), a group of Jehovah’s Witnesses were denied a permit to use a city park for Bible talks, although other political and religious groups had been allowed to put the park to analogous uses. Concluding that the permit was denied because of the city’s “dislike for or disagreement with the Witnesses
The late Mr. Justice Black, who thought that picketing was not only a method of expressing an idea but also conduct subject to broad state regulation, nevertheless recognized the deficiencies of laws like Chicago’s ordinance. This was the thrust of his opinion concurring in Cox v. Louisiana, 379 U. S. 536 (1965):
“[B]y specifically permitting picketing for the publication of labor union views [but prohibitingPage 98other sorts of picketing], Louisiana is attempting to pick and choose among the views it is willing to have discussed on its streets. It thus is trying to prescribe by law what matters of public interest people whom it allows to assemble on its streets may and may not discuss. This seems to me to be censorship in a most odious form, unconstitutional under the First and Fourteenth Amendments. And to deny this appellant and his group use of the streets because of their views against racial discrimination, while allowing other groups to use the streets to voice opinions on other subjects, also amounts, I think, to an invidious discrimination forbidden by the Equal Protection Clause of the Fourteenth Amendment.” Id., at 581.
We accept Mr. Justice Black’s quoted views. Cf. NLRB v. Fruit & Vegetable Packers, 377 U. S. 58, 76 (1964) (Black, J., concurring).
II
This is not to say that all picketing must always be allowed. We have continually recognized that reasonable “time, place and manner” regulations of picketing may be necessary to further significant governmental interests. Cox v. New Hampshire, 312 U. S. 569, 575-576 (1941); Poulos v. New Hampshire, 345 U. S. 395, 398 (1953); Cox v. Louisiana, 379 U. S., at 554-555; Cox v. Louisiana, 379 U. S. 559 (1965); Adderley v. Florida, 385 U. S. 39, 46-48 (1966). Similarly, under an equal protection analysis, there may be sufficient regulatory interests justifying selective exclusions or distinctions among pickets. Conflicting demands on the same place may compel the State to make choices among potential users and uses. And the State may have a legitimate interest in prohibiting some picketing to protect public order. But these justifications for selective exclusions
Ill
In this case, the ordinance itself describes impermissible picketing not in terms of time, place, and manner, but in terms of subject matter. The regulation “thus slip [s] from the neutrality of time, place, and circumstance into a concern about content.”6 This is never permitted. In spite of this, Chicago urges that the ordinance is not improper content censorship, but rather a device for preventing disruption of the school. Cities certainly have a substantial interest in stopping picketing which disrupts a school. “The crucial question, however, is whether [Chicago’s ordinance] advances that objective in a manner consistent with the command of the Equal Protection Clause.” Reed v. Reed, 404 U. S., at 76. It does not.
Similarly, we reject the city’s argument that, although it permits peaceful labor picketing, it may prohibit all nonlabor picketing because, as a class, nonlabor picketing is more prone to produce violence than labor picketing.7 Predictions about imminent disruption from picketing in
The Equal Protection Clause requires that statutes affecting First Amendment interests be narrowly tailored to their legitimate objectives. Williams v. Rhodes, 393 U. S. 23 (1968); see generally Dunn v. Blumstein, 405 U. S., at 342-343.8 Chicago may not vindicate its interest in preventing disruption by the wholesale exclusion of picketing on all but one preferred subject. Given what Chicago tolerates from labor picketing, the excesses of some nonlabor picketing may not be
The judgment is
Affirmed.

Occasionally, thereafter, Mosley would picket across the street, outside the 150-foot zone. At the hearing below, Mosley testified that “when I was across the street from the school, 150 feet away, you cannot hardly see me. The question that all of the people asked me was, ‘Where is the school located?’ They don’t even see the school across the street, you know. So, what it does, it takes away a certain amount of the effectiveness .... [W]hen I am across the street, I am sort of out of the picture . . . .” App. 24-25.

By its terms, the statute exempts “the peaceful picketing of any school involved in a labor dispute.” It is undisputed that this exemption applies only to labor picketing of a school involved in a labor dispute.

The city notes in its brief, pp. 28-30:
“Although the civil rights movement has understandably endeavored to press into its service the constitutional precedents developed in labor relations litigation, there are important differences between labor picketing and picketing by civil rights groups. . . . Labor picketing is now usually token picketing. ... It seldom leads to disruption of the public peace, hardly ever to window smashing, arson. Labor picketing can be carried on without interrupting classes or even distracting the students. ... As we all know, student demonstrations at schools — and even such demonstrations by parents and 'concerned citizens’ — are utterly different. Mass picketing, sit-ins, smashed windows have been the order of the day. The very purpose of such demonstrations often is to bring the educational process to a halt.”

In a variety of contexts we have said that “even though the governmental purpose be legitimate and substantial, that purpose cannot be pursued by means that broadly stifle fundamental personal liberties when the end can be more narrowly achieved.” Shelton v. Tucker, 364 U. S. 479, 488 (1960). This standard, of course, has been carefully applied when First Amendment interests are involved. E. g., Schneider v. State, 308 U. S. 147, 164 (1939); De Jonge v. Oregon, 299 U. S. 353, 364-365 (1937); Cantwell v. Connecticut, 310 U. S. 296, 307 (1940); NAACP v. Button, 371 U. S. 415, 438 (1963); Cox v. Louisiana, 379 U. S. 559, 562-564 (1965); United States v. O’Brien, 391 U. S. 367 (1968).

Chicago argued below that the labor exemption in the ordinance was necessitated by federal pre-emption of the regulation of labor relations. The city now recognizes that the National Labor Relations Act specifically exempts States and subdivisions (and therefore cities and their public school boards) from the definition of “employer” within the Act. 29 U. S. C. § 152. Nevertheless, Chicago urges that the pre-emption argument still has “some merit.” It argues that “since observance by employees of private employers of picket lines of public employees can have repercussions in the federal sphere, the City was well advised to avoid this quagmire of labor law and labor relations by exempting labor picketing from the ordinance.” Reply Brief 12. This attenuated interest, at best a claim of small administrative convenience and perhaps merely a confession of legislative laziness, cannot justify the blanket permission given to labor picketing and the blanket prohibition applicable to others.
