Charlie 2 (also known as C-2, Combat Base C-2, C-2 Strongpoint and Firebase Charlie 2) is a former U.S. Marine Corps, U.S. Army and Army of the Republic of Vietnam (ARVN) firebase north of Đông Hà in central Vietnam.

The base was established 12.5 km northwest of Đông Hà and 5 km southeast of Con Thien to protect the land route to Con Thien and particularly the C-2 bridge immediately north of the base.

[1][2] By December 1967 all bunkers at C-2 had been completed and all minefields laid and perimeter barbed wire emplaced.

[5] On 21 May 1971 30 US infantrymen, many from Company A, 1st Battalion, 61st Infantry Regiment, were killed when a People's Army of Vietnam (PAVN) 122mm rocket hit their bunker at Charlie 2.
