Marcos Alcocer was a 17th-century Jesuit priest and poet from Quito, and brother to Hernando and Pedro Alcocer. He was admired for both the musical quality of his verses and his personal virtues. A professor of theology at the University of San Gregorio in Quito, Marcos authored two Latin theological treatises—De Divinis attributis (1658) and De Visone Dei (1665)—which are preserved in the national library and were written for the instruction of his students.
