Luis de Rosas (died January 25, 1642) was a soldier who served as the ninth Spanish Governor of New Mexico from 1637 until 1641, when he was then imprisoned and assassinated. During his administration, de Rosas clashed with the Franciscans, mainly because of his handling of the indigenous Americans, whom he forced to work for him or sold them as slaves. The Franciscans promoted a revolt of the citizens of New Mexico against him. De Rosas was imprisoned after an investigation relating to his position as governor. He was killed by soldiers while in prison.
