Unia Racibórz was founded on 27 April 1946 as a men's team. Its initial name was Klub Sportowy Plania Racibórz. The club has undergone several name changes. From June 1949 to November 1949 it was named ZKS Chemik Racibórz, then it was called ZKS Unia Racibórz, and KS Unia Racibórz up to the 1997–98 season before adopting the current name RTP Unia Racibórz. Until 2001, the year the women started training, the club had only a men's football team. The women's team was registered for league play in the 2002–03 season. In January 2008, after discrepancies over the use of finances, the men's section split from RTP Unia and took the name KP Unia Racibórz. Thus RTP Unia Racibórz became exclusively a women's football club.
