Suibne mac Colmáin (died 600) was a King of Uisnech in Mide of the Clann Cholmáin.
He was the son of Colmán Már mac Diarmato (died 555/558), also King of Uisnech.
[3] He may also be the Suibne referred to in the Baile Chuind (The Ecstasy of Conn)[4] The annals and other king lists do not give him this title, however.
He was slain in 600 at Brí Dam on the Suaine (near modern Geashill, County Offaly)[5][6] by his uncle, the high king Áed Sláine mac Diarmato (died 604) of the Síl nÁedo Sláine, treacherously according to the Life of St. Columba by Adomnán.
[7] Suibne's sons Conall Guthbinn mac Suibni (died 635) and Máel Dóid mac Suibni (died 653) were also kings of Uisnech.
