Avishai Raviv (Hebrew: אבישי רביב; born 8 June 1967) is a former agent of Israel's Shin Bet (Shabak), Israel's domestic intelligence service, whose mission was to monitor the activities of right-wing extremists.

[2] Raviv was filmed at a public demonstration with a poster of Israeli prime minister Yitzhak Rabin in an SS uniform prior to Rabin's murder.

[1] Raviv allegedly knew of Yigal Amir's plans to assassinate Rabin.

After Rabin was assassinated, the journalist Amnon Abramowitch revealed that Raviv was an agent of the Shabak.

Raviv mounted a successful defense on the grounds that he had just been doing his job and events had spun out of control.
