Sportklub Slovan Hütteldorfer Athletikclub Wien, better known as SK Slovan HAC, is an Austrian football club located in Hütteldorf, Vienna, Austria.
Sk Slovan HAC was founded on 11 January 1902 as Sportovni Klub Slovan ve Vídni - better known as SK Slovan - by the Czech minority in Vienna. They were promoted to the Austrian First Division in 1923, and built a new stadium - the České srdce (now known as the Generali Arena). The stadium was so large that it caused the club financial problems.
The club was relegated in 1928/29 season, but was in the first division again in 1930. They again achieved promotion to the first division in 1949/50 as AC Sparta. In 1960, the club merged with ÖMV Olympia 33 and the club was known as SK Slovan-Olympia. In 1976, they merged with Hütteldorfer AC founded in 1911, and was thereafter known as SK Slovan-Hütteldorfer AC. They have mostly played in the Wiener Stadtliga since the 1980s and 90s.
