National Association for the Advancement of Colored People (NAACP) is a civil rights organization in the United States. It works to end discrimination against blacks and other minority groups.

The NAACP achieves many goals through legal action. It played an important part in the 1954 ruling of the Supreme Court of the United States that segregation of blacks in public schools is unconstitutional. Thurgood Marshall, a lawyer from the NAACP Legal Defense and Educational Fund, presented the argument in the case, known as Brown v. Board of Education of Topeka.

The organization also achieves its goals through legislative action. It played a leading role in obtaining passage of the Civil Rights Act of 1957, which protects the right to vote. This act established the Civil Rights Division of the Department of Justice and the Commission on Civil Rights. The NAACP worked for passage of the Civil Rights Act of 1964, which forbids discrimination in public places. This law established the Equal Employment Opportunity Commission (EEOC). The association also helped bring into law the Voting Rights Act of 1965, which protects voter registration.

The NAACP was founded in 1909 by 60 black and white citizens. In 1910, the organization began to publish Crisis, a magazine about blacks who have achieved success in the arts, business, and other fields.
