Mount Blackburn () is a massive, flat-topped mountain, 3,275 metres (10,745 ft) high, standing just east of the Scott Glacier where it surmounts the southwest end of California Plateau and the Watson Escarpment, in the Queen Maud Mountains.
It was discovered by and named for Quin A. Blackburn, geologist, leader of the Byrd Antarctic Expedition geological party which sledged the length of Scott Glacier in December 1934.
