Fußball-Club Augsburg 1907 e. V., commonly known as FC Augsburg ([ɛfˌt͡seː ˈaʊ̯ksbʊʁk] (listen)) or Augsburg, is a German football club based in Augsburg, Bavaria. FC Augsburg play in the Bundesliga, the top tier of the German football league system. The team was founded as Fußball-Klub Alemania Augsburg in 1907 and played as BC Augsburg from 1921 to 1969. With over 18,800 members, it is the largest football club in Swabian Bavaria.

The club has spent most of its history fluctuating between the second and third divisions, with disappointment striking in the early 2000s when Augsburg were relegated to the fourth division for two seasons. However, the club experienced a surge following this setback, and was eventually promoted to the Bundesliga for the first time in 2011, where it has remained ever since. Augsburg have consolidated their Bundesliga status in the 2010s, finishing a record high fifth in the 2014–15 season before several mid-table finishes, and made their European debut in the 2015–16 UEFA Europa League, with the club reaching the Round of 32 before being knocked out by Liverpool 1–0 on aggregate.

Since 2009, FC Augsburg's stadium has been the 30,660 capacity WWK ARENA, located south of Augsburg city centre and easily accessible via tram. The club, known as the Fuggerstädter or simply as FCA, receive strong home support with an average attendance of 28,709 in the 2019–20 Bundesliga season (93.6% of stadium capacity). It is a single tier stadium with a standing terrace behind one of the goals, known as the Ulrich-Biesinger-Tribüne, and three seated stands with a standing section in the opposite corner to the Ulrich-Biesinger-Tribüne for away fans.

Augsburg maintains fierce local rivalries with Ingolstadt and TSV 1860 Munich. Matches between these clubs typically attract large crowds, and a match in 1973 at 1860 Munich set the all-time spectator record for the Olympic Stadium. FCA regularly sell out their local Bavarian derby against Bayern Munich.
