Eintracht Frankfurt e.V. ([ˈaɪntʁaxt ˈfʁaŋkfʊʁt] (listen)) is a professional sports club based in Frankfurt, Hesse, Germany. It is best known for its football club, which was founded on 8 March 1899. The team is currently playing in the Bundesliga, the top tier of the German football league system. Eintracht have won the German championship once, the DFB-Pokal five times, the UEFA Europa League twice and finished as runner-up in the European Cup once. The team was one of the founding members of the Bundesliga at its inception and has spent a total of 54 seasons in the top division, thus making them the seventh longest participating club in the highest tier of the league.

The club's initial games from 1899 to 1906 were played on the former Hundswiese field, whose present day location would be near Hessischer Rundfunk. Following new regulations that pitches needed to be surrounded by a fence for the purpose of official games, the team established a new pitch by the Eschersheimer Landstraße called Victoriaplatz in 1906, for which they purchased stands at a price of 350 marks in 1908. From 1912 the team moved to a new ground at Roseggerstraße in Dornbusch with more facilities, before relocating to the former Riederwaldstadion in 1920 following the fusion of Frankfurter FV and Frankfurter Turngemeinde von 1861. Since 1925 their stadium has been the Waldstadion, which is currently named Deutsche Bank Park for sponsorship reasons.

Eintracht Frankfurt have enjoyed some success in the Bundesliga, having either won or drawn more than three-quarters of their games as well as having finished the majority of their seasons placed in the top half of the table, but also having the highest number of losses in the league (657). With an average attendance of 47,942 since 2013 the team also boasts one of the highest attendance ratings in the world and the eighth highest out of the 36 Bundesliga and 2. Bundesliga teams. The player with the highest number of appearances (602) in the Bundesliga, Charly Körbel, spent his entire senior career as a defender for Eintracht Frankfurt. The club's primary rival is local club Kickers Offenbach, although, due to spending most of their history in different divisions, the two have only played two league matches within the last 40 years.
