The Woolworth's Lunch Counter sit-ins were a series of nonviolent protests that took place in 1960 at several F.W. Woolworth stores across the United States. The most well-known sit-in occurred at the lunch counter in Greensboro, North Carolina, where four African American college students, known as the "Greensboro Four" - Ezell Blair Jr., David Richmond, Franklin McCain, and Joseph McNeil - sat down at the whites-only lunch counter and refused to leave until they were served.

These sit-ins were part of a larger civil rights movement aimed at ending racial segregation in public spaces. The Woolworth's sit-ins sparked a wave of similar protests across the country, leading to more than 70,000 people participating in sit-ins at over 100 cities. The protests eventually led to Woolworth's desegregating its lunch counters in July 1960.

The Woolworth's Lunch Counter sit-ins were instrumental in raising awareness about racial inequality and segregation in the United States. They played a significant role in energizing the civil rights movement and inspiring future generations of activists to fight for equality and justice.
