Cigar Factory, Industrial heritage site in Charleston, United States.

The Cigar Factory is a five-story brick building at 701 East Bay Street in Charleston, built in 1881 and opened in 1882 as the Cotton Mill of Charleston. It has segmental arch windows and wooden support posts. A $30 million redevelopment began in 2014, and by 2017 the building was mostly leased; it now holds restaurants, salons, an event venue and an ophthalmologist's office.

The building was first constructed as a cotton mill in 1881 and was converted into an American Cigar Company facility in 1912. It became Charleston's largest private employer during the 1930s.

The factory became a gathering place during the 1945-1946 labor strike, where workers adapted the song 'We Shall Overcome' that would later define the civil rights movement. This connection transformed the building into a symbol of worker activism and social change.

The building occupies the block bounded by East Bay, Columbus and Blake Streets in downtown Charleston, a short walk from the city's other historic sites. A $30 million redevelopment begun in 2014 was largely leased out by 2017, and the former industrial floors now hold restaurants, salons, an event venue and an ophthalmologist's office.

During peak operations, the factory produced popular Certified Cremo and Roi-Tan cigars, leading workers to affectionately call the building Cremo College. This nickname reflected how deeply the factory had shaped the lives and identities of those who worked there.
