Vartholomio (Greek: Βαρθολομιό) is a town and a former municipality in Elis, West Greece, Greece.

Its population was 5,899 in 2011, of which 3,603 lived in the town proper. The municipal unit covers the southern part of the hilly Kyllini peninsula, and the plains to the southeast. The town Vartholomio is in the plains, on the right bank of the river Pineios, which flows into the Ionian Sea south of the town.
