Salah Al-Deen Siamand Tahir () (born 13 July 1981) is a former Iraqi football player of Kurdish ethnicity, who last played for Erbil.
Salah Al-Deen played in both central defence and in a deep midfield position.
He played for the Iraq B team in Indonesia in 2000, before winning the 2000 AFC Youth Championship in Tehran, Iran, three months later. In the early games of that tournament, Saimand was never a regular, making only one substitute appearance before he was introduced at half-time against Korea; Iraq eliminated Korea and advanced to the semi-final. The Iraqi team manager kept the same formation for the semi-final match against Iran, giving Siamand his first start; he missed a penalty in the shoot-out win.
After the final win over Japan in the final, he was given an unexpected call up to the Iraqi national team by Milan à ½ivadinoviÃÂ, making his debut on January 31, 2000, in a 0âÂÂ0 draw with Lebanon in Beirut.
