Hackamore (formerly Jaquina) is an unincorporated community in Modoc County, California. It is located on the Southern Pacific Railroad west of Alturas, at an elevation of 4705 feet (1434 m).
A post office operated at Hackamore from 1903 (having been transferred from Stobie) to 1904.
Hackamore was the site of a Civilian Conservation Corps camp during the 1930s. Camp residents built many miles of roads and telephone lines in the region and assisted in the mapping of Lava Beds National Monument.
