Wells W. Spicer (1831 – 1885) was an American journalist, prospector, politician, lawyer and judge whose legal career immersed him in two significant events in frontier history: the Mountain Meadows massacre in the Utah Territory in 1857; and the 1881 shootout commonly known as the Gunfight at the O.K. Corral in Tombstone, Arizona Territory. After he left Tombstone, he returned to prospecting. He disappeared in 1885 or 1887.
