Kolejowy Klub Sportowy Czarni Sosnowiec, commonly referred to as Czarni Sosnowiec, is a football club from Sosnowiec, Poland. The club was founded in 1924, and its home ground is the Jan Ciszewski's Stadium. Primarily focused on its women's department, Czarni had operated a men's section in the past.

Women's football team, founded 5 September 1974, holds the Polish record for championship titles won, with 13 titles to its name. After some financial problems the club was in the 2007–08 season relegated from the Ekstraliga Kobiet; in 2008–09 they reached the promotion playoffs but lost convincingly. With the expansion of the Ekstraliga in 2010–11 a second-place was enough to ensure direct promotion again. In 2021, they won their first championship in over twenty years.
