Colonel Albert Jennings Fountain (October 23, 1838 – disappeared February 1, 1896) was an American attorney who served in the Texas Senate and the New Mexico House of Representatives. Following a purge of corruption among cattle rustlers that Fountain investigated and prosecuted, he and his eight-year-old son Henry disappeared near White Sands, New Mexico Territory. Their bloodstained wagon and other evidence of an ambush were recovered, but the bodies were never found. Suspicion centered on two rival landowners, Oliver M. Lee and Albert Bacon Fall. Lee and two employees were tried for the murder of Henry Fountain, but acquitted after a defense by Fall. No charges were ever filed for the death of Albert Fountain.
