Omagh Area C was one of the four district electoral areas in Omagh, Northern Ireland which existed from 1973 to 1985. The district elected seven members to Omagh District Council, and formed part of the Mid Ulster constituencies for the Northern Ireland Assembly and UK Parliament.

It was created for the 1973 local elections, and contained the wards of Dergmoney, Drumragh, East, Fairgreen, Killyclogher, Strule and West. It was abolished for the 1985 local elections and mostly replaced with the Omagh Town DEA, with Killyclogher moving to the Mid Tyrone DEA.
