Ekrem Hayyam Dağ (born 5 December 1980) is a football coach and a former player.

Dağ started his career at SVL Flavia Solva but joined the youth team of SK Sturm Graz in 1997 where he made his professional debut four years later.

Dağ grew up in Leibnitz and holds Austrian and Turkish dual nationality, making him eligible for both countries.

Dağ chose Austria over Turkey, and was due to make his debut on 31 May 2009; however this dream was stopped by injury.

Dağ was called up to the Austria national team again on 10 October 2009 for the game against Lithuania,[3] but was an unused substitute.
