Motherwell boss Stephen Robinson has made defender Charles Dunne his seventh signing of the summer.
The 24-year-old former Wycombe Wanderers and Blackpool player moves to Fir Park after spending last season with Oldham Athletic.
Robinson told the Motherwell website: "Charles is a player who I have worked with before. He’s a big, strong athlete, who can play in a number of different defensive positions. He adds real pace to the back four and he’ll provide real competition for places back there."
