Mount Goodsir (or the Goodsir Towers) is the highest mountain in the Ottertail Range, a subrange of the Park Ranges in British Columbia.

The mountain has two major summits, the South Tower (the higher summit) and the North Tower, 3,525 metres (11,565 ft).

[5] The mountain was named by James Hector in 1859 after two brothers, John Goodsir, a professor of anatomy at the University of Edinburgh, and Harry Goodsir, a surgeon on the ship HMS Erebus.

[2][6] The standard route on the South Tower is the southwest ridge, a straightforward but long climb (Grade III), which consists primarily of non-technical terrain, but includes short sections of narrow ridge graded YDS 5.4.

Access to any route on either Tower requires a long hike.
