Indrechtach mac Muiredaig Muillethan (died 723)[1] was a King of Connacht from the Uí Briúin branch of the Connachta.
He was the son of Muiredach Muillethan mac Fergusso (died 702), a previous king.
The king-lists for this period are contradictory but the Laud Synchronisms give him a reign of 16 years.
[4] One event which occurred during his reign was the defeat of the Corco Baiscind, a Thomond tribe, by the Connachta in 721.
A daughter of Indrechtach named Medb is said by the Banshechas to have married Áed Oirdnide and to have been the mother of Niall Caille
