Enoch Steen (1800 – 1880) was a United States military officer and western explorer. He joined the United States Army in 1832, serving at posts throughout the United States, including many remote locations in the west. During his military service, Steen explored parts of the western United States including large areas of southern New Mexico and southeastern Oregon. He served as the commander of several Union Army forts during the American Civil War. Today, there are landmarks in Oklahoma, Oregon, and New Mexico named in his honor; however, many of the place names are misspelled as Stein.
