The Honniasont (Oniasont, Oniassontke, Honniasontkeronon) were a little-known Indigenous people of the Northeastern Woodlands originally from eastern Ohio, western Pennsylvania, and West Virginia. They appear to have inhabited the upper Ohio River valley, above Louisville, Kentucky.

The Honniasont language may have been considered an Iroquoian language. Charles Hanna believed their name, first appearing as Oniasont on 17th-century French maps, to be a variation of the name of the tribe recorded in West Virginia and western Virginia at the same time period, as Nahyssan and Monahassanough, i.e. the Tutelo, a Siouan language speaking people.
