Diego de Alcaraz was a Spanish captain during the early days of the colony of New Spain. He is remembered for his brutality in collecting Native Americans as slaves in the regions of what is now northern Mexico and the southwest United States. In 1536, he was the first Spanish official to meet the survivors of the failed Pánfilo de Narváez expedition. Alcaraz was killed by Indians while on expedition with Francisco Vásquez de Coronado.
