La Junta Indians is a collective name for the Indians living near the junction (la junta) of the Rio Grande and Conchos rivers on the borders of present day Texas and Mexico. These people were first visited by Alvar Nunez Cabeza de Vaca in 1535. In the eighteenth century they mostly lost their tribal identifications and became part of the mestizo population of Mexico or joined other Indian groups.
