The Porvenir massacre was an incident on January 28, 1918 outside the village of Porvenir in Presidio County, Texas, in which Texas Rangers, U.S. Cavalry soldiers, and local ranchers killed 15 unarmed Mexican American boys and men. The Texas Rangers Company B was sent to the area to stop banditry after the Brite Ranch raid. Despite having no evidence that the Porvenir villagers were involved in recent thefts or the killings of ranchers, the Rangers separated fifteen men and boys from the rest of the village and shot them on a nearby hill.
