Bearcat Base (also known as Bearcat, Camp Martin, Camp Cox or Long Thanh North) is a former U.S. Army base near the city of Biên Hòa in Đồng Nai province in southern Vietnam.

Bearcat was originally a French airfield, later used by the Japanese during World War II.

Early in the Vietnam War, the 1st Special Forces established a base there.

The camp was located on Route 15, 16 km southeast of Biên Hòa.
