Dawn at Socorro is a 1954 American Western film directed by George Sherman and starring Rory Calhoun and Piper Laurie. It was produced and distributed by Universal Pictures. The film is set mostly in Lordsburg, New Mexico, and the spoken introduction says the story is based on an actual shootout in the town in 1871. But no such incident happened there. The plot is actually a thinly veiled fictionalization of the famous 1881 shootout near the OK Corral in Tombstone, Arizona, which pitted the Earp brothers and Doc Holliday against the Clanton Gang.
