1215 Boyer is a stony S-type asteroid from the asteroid belt. It was discovered by French astronomer Alfred Schmitt at Algiers Observatory, Algeria on 19 January 1932, and received the provisional designation 1932 BA. Eight days later, it was independently discovered by astronomer Karl Reinmuth at the Heidelberg Observatory.
Schmitt named the asteroid in honor of his colleague at Algiers Observatory, Louis Boyer (1901–1999), who worked extensively on minor planets and comets and discovered 40 minor planets at the same observatory.
