Pedro Armillas Garcia (9 September 1914 – 11 April 1984) was Spanish academic anthropologist, archaeologist, and an influential pre-Columbian Mesoamerica scholar of the mid-20th century. As an archaeologist he was known both for his fieldwork and excavations at numerous sites in central and northern Mexico, and his contributions in archaeological theory. His study of how Mesoamerican agriculture and subsistence modes of production influenced the development of Mesoamerican cultures was a pioneering one, and he was one of the earliest to investigate pre-Columbian irrigation and hydraulic systems.
