The Chinese Exclusion Act was a United States federal law enacted on 6 May 1882 that prohibited the immigration of Chinese laborers into the United States. It was the first - and, to date, only - federal law to explicitly restrict immigration on the basis of race and national origin. The law suspended the entry of Chinese laborers for ten years, barred Chinese immigrants from naturalization, and required Chinese residents already in the country to carry identification papers. It was extended and strengthened by subsequent legislation, including the Scott Act (1888) and the Geary Act (1892), and was not repealed until the Magnuson Act of 1943.

The act emerged from prolonged social and economic tensions in the American West following the completion of the First Transcontinental Railroad in 1869. Chinese laborers, who had constituted a significant portion of the Central Pacific Railroad's workforce, remained in California and other western states in large numbers. Amid an economic downturn in the 1870s, organized labor and political movements in California campaigned against Chinese employment, arguing that Chinese workers suppressed wages and took jobs from white workers. The Workingmen's Party of California, led by Denis Kearney, was among the most prominent voices in this agitation.

Historians broadly agree on the basic legislative and demographic facts surrounding the act. The law's effects on Chinese immigration were immediate and severe: Chinese immigration, which had numbered in the tens of thousands annually in prior decades, dropped to near zero within years of the act's passage. Enforcement created a system of documentation and surveillance that applied specifically to Chinese residents, including those with legal status.

Scholarly debate continues on several questions: the relative weight of economic versus racial motivation in the law's passage; the role of organized labor as distinct from populist nativism; the degree to which the act influenced subsequent restrictive immigration legislation, including the Immigration Act of 1924; and how the episode should be evaluated in relation to broader patterns of American immigration and civil rights history. The act's contemporary relevance - as a precedent, cautionary example, or object of comparison to later immigration restrictions - remains actively contested.

- The act as product of racial animus: A number of historians and commentators argue that economic justifications were secondary to racial hostility, and that the law is best understood as an expression of white supremacist politics that targeted Chinese immigrants specifically because of their perceived unassimilability. See chinese-exclusion-act-racial-animus-viewpoint.

- The act as labor protectionism: Some analysts, including certain labor historians, have argued that the political coalition behind the act was driven primarily by working-class economic anxiety, with racial framing functioning as the vehicle for economic grievance rather than its root cause. See chinese-exclusion-act-labor-protectionism-viewpoint.

- The act as a cautionary precedent for state power: A libertarian and civil-liberties-oriented reading holds that the act illustrates the danger of granting government broad authority to exclude or classify persons by national origin or ethnicity, and draws lessons relevant to later immigration debates. See chinese-exclusion-act-state-power-viewpoint.

- The act in the context of national sovereignty: A minority of commentators, particularly in debates over immigration restriction more broadly, have argued that the act, whatever its flaws in implementation, reflected a legitimate exercise of national sovereignty over immigration and labor markets. See chinese-exclusion-act-national-sovereignty-viewpoint.

- Formal congressional apology: Congress passed resolutions in 2011 and 2012 expressing regret for the act, with debate over the scope, meaning, and adequacy of such resolutions - and whether they constituted a full apology. See chinese-exclusion-act-congressional-apology-controversy.

- Comparison to post-2001 national-origin restrictions: Commentators and litigants have disputed whether the Chinese Exclusion Act is an appropriate legal or historical precedent for later executive actions restricting immigration on national-origin grounds.
