Vietcong is a 2003 tactical first-person shooter video game developed by Pterodon and 2K Czech, published by Gathering of Developers. It is set during the Vietnam War in 1967.

The expansion pack Vietcong: Fist Alpha was released in 2004 and was bundled with Vietcong as Vietcong: Purple Haze for the PC. Vietcong: Purple Haze was also released in 2004 for the PlayStation 2 and Xbox, ported by Coyote Games. An official add-on "Red Dawn" was released as a free downloadable content. A sequel to the game, Vietcong 2, was released in 2005.

The player takes on the role of Sergeant First Class Steve R. Hawkins, assigned to the United States Special Forces ("Green Berets") camp at a strategic location of Nui Pek in South Vietnam, a few miles near the Cambodian border. Hawkins and his A-Team (an LLDB guide Le Duy Nhut, the medic Joe Crocker, the demolition specialist Thomas Bronson, the radioman C.J. Defort and the team's machine gunner Hornster) carry out a series of various missions against the Vietcong and North Vietnamese forces. The game ends in a massive North Vietnamese attack on the team's base camp.
