Johns Hopkins Glacier is a 12-mile (19 km) long glacier located in Glacier Bay National Park and Preserve in the U.S. state of Alaska. It begins on the east slopes of Lituya Mountain and Mount Salisbury, and trends east to the head of Johns Hopkins Inlet, 1 mile (1.6 km) southwest of the terminus of Clark Glacier and 79 miles (127 km) northwest of Hoonah. It was named after Johns Hopkins University in Baltimore, Maryland in 1893 by Harry Fielding Reid. It is one of the only advancing tidewater glaciers of the Fairweather Range.
