Until the end of 2013, the club also had a department in American football, but it was dissolved because it lacked the youth team required in order to hold a men's team. FC St. Pauli has 22,000 members as of 1 July 2015.
The men's professional football team dropped down to the Regionalliga in 2003, at that time the third highest football division in Germany and remained there for four years. In 2007, they won promotion back to the 2. Bundesliga and in 2010, they were promoted to the Bundesliga. Since the 2011–12 season, they have played in 2. Bundesliga, the second-highest division in Germany.
