James Warren "Jim" Jones (May 13, 1931 – November 18, 1978) was the founder and leader of the Peoples Temple, which is best known for the November 18, 1978 death of more than 900 Temple members in Jonestown, Guyana along with the deaths of nine other people at a nearby airstrip and in Georgetown.

Jones was born in Indiana and started the Temple in that state in the 1950s. Jones and the Temple later moved to California, and both gained notoriety with the move of the Temple's headquarters to San Francisco in the mid-1970s.

The greatest single loss of American civilian life in a non-natural disaster until the events of September 11, 2001, the tragedy at Guyana also ranks among the largest mass suicides in history. One of those who died at the nearby airstrip was Leo Ryan, who became the only Congressman murdered in the line of duty in the history of the United States.
