Ólchobar mac Duib-Indrecht (died 805) was a supposed King of Munster from the Eóganacht Áine branch of the Eóganachta.
His last paternal ancestor to hold the throne was Cúán mac Amalgado (died 641), five generations previous.
His great-grandfather Uisnech had been the brother of another King Eterscél mac Máele Umai (died 721).
This was broken by the reign of Máel Dúin mac Áedo (died 786) of the Eóganacht Locha Léin branch which ruled in Iarmuman (West Munster).
The definitive restoration of the rule of the inner circle is considered to be the ordination of Artrí mac Cathail (died 821) of the Eóganacht Glendamnach branch as king in 793.
