Joseph Alexander McChristian (October 12, 1914 – May 13, 2005) was a United States Army Major General and the assistant chief of staff for intelligence, Military Assistance Command, Vietnam (J-2, MACV) (then commanded by General William Westmoreland) from July 13, 1965 to June 1, 1967. As J-2, MACV, he predicted that the North Vietnamese would attack in full force, which they did during the 1968 Tet offensive. His prediction was unpopular because the official policy was that US and South Vietnamese forces were winning the war.
