Sport-Club Freiburg e.V., commonly known as SC Freiburg ([ʔɛs ˈtseː ˈfʁaɪbʊɐ̯k]) or just Freiburg, is a German football club, based in the city of Freiburg im Breisgau, Baden-Württemberg. It plays in the Bundesliga, having been promoted as champions from the 2. Bundesliga in 2016. Between 1954 and 2021, Freiburg's stadium was the Dreisamstadion. The club moved to the newly built Europa-Park Stadion in 2021. Volker Finke, who was the club's manager between 1991 and 2007, was the longest-serving manager in the history of professional football in Germany. Joachim Löw, former manager of the Germany national team, is the club's second-highest all-time leading goal scorer with 81 goals in 252 games during his three spells at the club, behind Nils Petersen.
The club traces its origins to a pair of clubs founded in 1904: Freiburger Fußballverein 04 was organised in March of that year; FC Schwalbe Freiburg just two months later. Both clubs underwent name changes, with Schwalbe becoming FC Mars in 1905, Mars becoming Union Freiburg in 1906, and FV 04 Freiburg becoming Sportverein Freiburg 04 in 1909. Three years later, SV and Union formed Sportclub Freiburg, at the same time incorporating the griffin head.
In 1918, after the devastation of World War I, SC Freiburg entered a temporary arrangement with Freiburger FC to be able to field a full side called KSG Freiburg. The next year, SC Freiburg associated themselves with FT 1844 Freiburg as that club's football department, until 1928 when they left to enter into a stadium-sharing arrangement with PSV (Polizeisportvereins) Freiburg 1924 that lasted until 1930 and the failure of PSV. SC Freiburg then picked up again with FT 1844 Freiburg in 1938. The club played on the highest level from 1928, first in the Bezirksliga Baden, then in the Gauliga Baden, from which they were relegated in 1934.
At the end of World War II, Allied occupation authorities disbanded most existing organizations in Germany, including football and sports clubs. The clubs were permitted to reconstitute themselves after about a year, but were required to take on new names in an attempt to disassociate them from the so-recent Nazi past. SC Freiburg was therefore briefly known as VfL Freiburg. By 1950, French-occupation authorities had let up enough to allow the clubs to reclaim their old identities. Finally, in 1952, SC Freiburg left FT Freiburg behind again.
