Mount King is a 2,868-metre (9,409-foot) mountain summit located in Yoho National Park, in the Canadian Rockies of British Columbia, Canada.

Its nearest higher peak is Mount Deville, 5.0 km (3.1 mi) to the northwest.

The mountain was named by Otto Koltz in 1886 for William Frederick King (1854–1916), a Canadian surveyor, astronomer, and civil servant.
