Boydell Glacier () is a glacier on Trinity Peninsula in northern Graham Land. It is about 9 miles (14 km) long, flowing southeastward from Detroit Plateau to enter Sjögren Inlet in Prince Gustav Channel north of the terminus of Sjögren Glacier and 6 miles (10 km) west of Mount Wild. It was mapped by the Falkland Islands Dependencies Survey from surveys (1960–61), and named by the UK Antarctic Place-Names Committee for James Boydell, English inventor of a steam traction engine, the first practical track-laying vehicle.
