2942 Cordie, provisional designation 1932 BG, is an asteroid from the inner regions of the asteroid belt, approximately 7 kilometers in diameter. It was discovered on 29 January 1932, by German astronomer Karl Reinmuth at Heidelberg Observatory in southwest Germany.

The asteroid has a long rotation period of roughly 80 hours.^[1] It was named after of Cordie Robinson, planetary geologist at the Harvard-Smithsonian Center for Astrophysics.^[2]
