Petermann Island is 1 mile long, lying 1 mile SW of Hovgaard Island in the Wilhelm Archipelago. It was discovered by a German expedition 1873-74, and named by Dallmann for August Petermann, noted German geographer and founder of Petermanns Mitteilungen. The US-ACAN has rejected the name Lund Island, applied by the BelgAE, 1897-99, in favor of the original naming.
