Vietnam Veterans Against the War (VVAW), founded on this day in 1967, is an American non-profit organization whose goal is to oppose U.S. policy and participation in the Vietnam War.

Today, the VVAW is a national veterans' organization that campaigns for peace, justice, and the rights of all United States military veterans. The VVAW is considered to be among the most influential anti-war organizations of the American Vietnam War era.

In January 1971, the VVAW sponsored the Winter Soldier Investigation to gather and present testimony from soldiers about war crimes being committed in Southeast Asia, intending to demonstrate that these resulted from American war policies.

The event was boycotted by most mainstream media, although the Detroit Free Press covered it daily. Later, the VVAW released "Winter Soldier", a 16mm black-and-white documentary film showing participants giving testimony at the 1971 hearing.
