The Town of St. George has a Town Meeting-Select Board-Manager form of local government.

This is the second most common form of local government in Maine. As municipalities grow in size and as state and federal regulations increase in number and complexity, many a municipality (currently, over 130) hires a manager to administer the town government. Under this form of government the Select Board continues to serve as the town's executive body; the primary difference is that they can attend more to issues of policy when they have an administrator to oversee the daily operations of the municipality.

Towns may adopt the town manager form of government either by adopting the state's Statutory Town Manager Plan or by adopting, via charter, their own custom-designed plan. In either case, the manager is responsible directly to the Select Board.
