Holden was settled in 1855 by a group of ten families sent out by the bishop of the local congregation of The Church of Jesus Christ of Latter-day Saints in Fillmore. Named Cedar Springs for the springs in the junipers that the community was built around. The town then assumed the name Buttermilk Fort because travelers passing through were encouraged to stop for a glass of cold buttermilk while resting. The town got its post office in 1864, and the town was renamed for Elijah E. Holden, a member of the Mormon Battalion who was one of the first settlers of Holden and died while caught in a snowstorm in 1858.
