Named in 1860 by Captain Richards, RN, after Admiral Sir Richard John Strachan (1760 - 1828), in association with other Royal Navy-related place names in the vicinity of Howe Sound. The pronunciation of the family name is "strawn", which explains why the feature is spelled "Mount Strahan" on early Admiralty Charts and on BC Lands maps through WW I.
