The Greensboro sit-ins were a series of nonviolent protests in February to July 1960, primarily in the Woolworth store—now the International Civil Rights Center and Museum—in Greensboro, North Carolina, which led to the F. W. Woolworth Company department store chain removing its policy of racial segregation in the Southern United States. While not the first sit-in of the civil rights movement, the Greensboro sit-ins were an instrumental action, and also the best-known sit-ins of the civil rights movement. They are considered a catalyst to the subsequent sit-in movement, in which 70,000 people participated. This sit-in was a contributing factor in the formation of the Student Nonviolent Coordinating Committee (SNCC).

The International Civil Rights Center & Museum (ICRCM) is located in Greensboro, North Carolina, United States. Its building formerly housed the Woolworth's, the site of a nonviolent protest in the civil rights movement. Four students from North Carolina Agricultural and Technical State University started the Greensboro sit-ins at a "whites only" lunch counter on February 1, 1960. The four students were Franklin McCain, Joseph McNeil, Ezell Blair Jr., and David Richmond. The next day there were twenty students. The aim of the museum's founders is to ensure that history remembers the actions of the A&T Four, those who joined them in the daily Woolworth's sit-ins, and others around the country who took part in sit-ins and in the civil rights movement. The Museum is currently supported by earned admissions and Museum Store revenues. The project also receives donations from private donors as a means of continuing its operations. The museum was founded in 1993 and officially opened its doors fifty years to the day after the sit-in movements in Greensboro NC.
