Tank Man (also known as the Unknown Protester or Unknown Rebel) is the nickname of an unidentified Chinese man who stood in front of a column of tanks leaving Tiananmen Square on June 5, 1989, the day after the Chinese military had suppressed the Tiananmen Square protests by force.

Internationally, it is considered one of the most iconic images of all time. Inside China, the image and the events leading up are subject to heavy state censorship.
