USCGC Mojave (WPG-47) was a 240-foot Tampa-class United States Coast Guard cutter in commission from 1921 until 1947.

The ship was launched by the Union Construction Company of Oakland, California on 7 September 1921, sponsored by Miss Elizabeth Haske of Oakland. She was commissioned at Oakland on 12 December 1921 as one of a new class of four ships which introduced the new principle of turbo-electric transmission.

Assigned to a permanent station at Honolulu, she served with the Bering Sea Patrol, and assisted in enforcing the ban on deep-sea sealing. Upon completion of her Bering Sea tour Mojave transferred to Boston and, in company with the cutters Modoc and Tampa, took up Grand Banks ice patrol duties. (The fourth ship of the class, Haida, spent the war in Alaskan waters.)

Mojave and her sister ships were gradually replaced by the new class of 2,200-ton cutters in 1930, although Mojave continued to operate out of Boston until 1933. She also occasionally took part in Coast Guard operations against the rumrunners between 1925 and 1930.

Weather patrols were instituted in 1940, and Mojave assumed rotating duty in 1941 as one of the Atlantic Ocean observation stations. This duty involved 21-day patrols in areas 10 miles square between Bermuda and the Azores. Prior to 1940 merchant ships had provided weather observation reports, but these had been curtailed when the outbreak of war forced ships of belligerent nations into radio silence.
