Rowardennan (Gaelic: Rubha Aird Eònain) is a small rural community on the eastern shore of Loch Lomond in Scotland. It is mainly known as the starting point for the main path up Ben Lomond.
Rowardennan is at the northern end of the public road, but the West Highland Way passes through the area and continues north along the side of the loch. Rowardennan has a hostel and camping for hikers on the West Highland Way. A small passenger ferry crosses the loch to Tarbet on the opposite shore.
