The Miles River is a 12.9-mile-long (20.8 km) tidal river in Talbot County, in the U.S. state of Maryland. It is a tributary of the Eastern Bay and is thus part of the Chesapeake Bay watershed. Miles River was originally called the St. Miles River; it derives its name from Saint Michael, the patron saint of Colonial Maryland.

Its watershed area is 54 square miles (140 km²), of which 12 square miles (31 km²) is open water, so it is 22% water. The predominant land use is agricultural with 22 square miles (57 km²), or 52% of the land area.
