Mount Tennent (Aboriginal: Tharwa) is a mountain with an elevation of 1,375 metres (4,511 ft) AHD in the southern part of the Australian Capital Territory in Australia.

Mount Tennent is named after a local bushranger, John Tennant1 who had a hideout on the slopes of the mountain in 1827.

In 2004, ACTEW announced that the creation of a large 159 gigalitres (5.6×109 cu ft) reservoir by damming the Gudgenby River below Mount Tennent, was one of three options being considered as part of the Future Water Options Project in order to provide improved reliability and increased supply of potable water for Canberra and the ACT.

Many people travel from the base of the mountain to the summit every day as a part of exercise and recreational habit.
