Black September Organization (BSO) is a Palestinian militant group notorious for their kidnapping of 11 Israeli athletes and slaughtering them during the 1972 Summer Olympics. The group took their name from the Black September event in Jordan when King Hussein declared martial law.

Black September started out with a small group of several men who desired to take revenge on King Hussein and the Jordanian Army. The group was most notable for assassinating Jordan's prime minister, Wasfi Tel, the Munich Massacre, and the 1973 New York Bomb Plot.

The incident in 1972 started the formation of groups like GSG 9, the GIGN and the reformation of the SAS.
