Ömer Aysan Barış (born 23 July 1982 in İzmit, Turkey) is a Turkish footballmidfielder. He started at youth team of a local team, Gölcükspor, after which he joined and played for 6 years for the city's biggest club, Kocaelispor at the top level and after the team relegated. He returned to the Süper Lig while playing at Bursaspor. He joined to the Ankaraspor in 2008, but due to injuries he only made a few appearances for them. Trabzonspor made a contract with him in October 2009 for 2.5 years in the last day of the temporary transfer window for the Ankaraspor players. This was because Ankaraspor is relegated from Super Lig by TFF after administrative partnership between Ankaraspor and Ankaragücü was found illegal. Towards the end of the 2009–10 season, coach Şenol Güneş declared in a press conference that Ömer Aysan is to be released from his contract as soon as possible.
