Curtiss Bay (64°2′S 60°47′W / 64.033°S 60.783°W / -64.033; -60.783 (Curtiss Bay)) is a bay about 4 nautical miles (7.4 km; 4.6 mi) wide, indenting the west coast of Graham Land between Cape Sterneck and Cape Andreas on the Davis Coast.

Curtiss Bay lies on the Davis Coast on the west side of the Antarctic Peninsula. It faces Trinity Island across the Orléans Strait. Cape Herschel on the Chavdar Peninsula defines the bay's western extremity. The Wright Ice Piedmont is to the southeast, and Lanchester Bay is to the east.

The name Bahia Inutil (useless bay) appearing on a 1957 Argentine chart is considered misleading; the bay has been used as an anchorage. The bay was renamed by the UK Antarctic Place-Names Committee (UK-APC) in 1960 for Glenn Curtiss, an American aeronautical engineer who pioneered seaplanes from 1911 onward.
