Colmán Rímid (or Colmán mac Báetáin) (died 604) was an Irish king who is included in some lists as a High King of Ireland. Colmán was the son of Báetán mac Muirchertaig (died 572), also considered to be a high king, and belonged to the Cenél nEógain branch of the northern Uí Néill. He ruled in Ailech from 578 to 602 His byname meant "the counter". The high kingship of Ireland rotated between the Cenél nEógain and Cenél Conaill branches in the late 6th century. He is said to have shared the High Kingship with Áed Sláine. The accession of Colmán and Áed to the high kingship is recorded in the annals in 598 They are also listed as kings in the king lists. They are however omitted from the earliest king list, the Baile Chuind (The Ecstasy of Conn), a late 7th-century Irish poem.  Fiachnae mac Báetáin of Ulaid may have been effectively king.
