Trabzonspor is a Turkish football club, from the Black Sea port city of Trabzon playing in the Turkish Premier Super League.
Trabzonspor was formed in 1967 in a merger of two local clubs. Many of the players from these teams became part of the team to win promotion to the top division, and helped Trabzonspor in their early years in the top flight. Along with three other Istanbul clubs known as the 'big three' (Galatasaray SK, Fenerbahçe SK, Beşiktaş J.K.), they are the only club to have won the Turkish title, earning a name as one of the "Big Four". Trabzonspor is as yet the only team from outside Istanbul to win it. Trabzonspor's nicknames are the "Bordeaux Blues" and the "Black Sea storm". Ziya Doğan has been unveiled as the new man in charge at Turkish UEFA Cup 2006-07 contenders Trabzonspor.
