Marcán mac Tommáin (died 653) was the 15th king of the Uí Maine.
In his time the Uí Maine were allied and ánmacTommásubject to the Ui Fiachrach Aidhne, a branch of the Connachta. They were ruled by Guaire Aidne mac Colmáin. The annals record that Marcán was slain in a battle in Airthir Seola by Cenn Fáelad mac Colgan and Máenach mac Báethíne of the Ui Briun in 653. The Annals of Ulster refer to it as a battle of the Connachta. Guaire's brother Loingsech mac Colmáin was ruling at this time and was being challenged by the Ui Briun.
