The semipalmated plover is a small plover. Charadrius is a Late Latin word for a yellowish bird mentioned in the fourth-century Vulgate. It derives from Ancient Greek kharadrios a bird found in ravines and river valleys. The specific semipalmatus is Latin and comes from semi, "half" and palma, "palm". Like the English name, this refers to its only partially webbed feet.
