Balmaha (Gaelic: Baile MoThatha) is a hamlet on the eastern shore of Loch Lomond in the council area of Stirling, Scotland.

The name Balmaha comes from the Gaelic for St Maha's Place which suggests the village may have ancient origins, perhaps as a hermit's residence. Today it is a popular tourist destination for picnickers and day trippers from Glasgow as well as walkers on the West Highland Way. Boat trips leave from Balmaha for Inchcailloch Island in the middle of the loch.
