The 20-year-old played in Monday's goalless draw with Scottish Premier League outfit Kilmarnock.
And that won him the Dunfermline-born player a one-year contract with the Division Three club.
Russell, who lives in nearby Helensburgh, started with the town's Ardencaple Boys Club before moving to Motherwell then Morton.
He broke into the first-team last season and made one start, plus nine appearances as a substitute, as Morton won the Second Division title.
Meanwhile, the Sons have re-signed two young players who have stepped up from their Under-19 squad - midfielder Alan Orr and former Hamilton Academical striker Mark McAlpine.
The Sons expect both to make their first-team debuts this season.
