The Baltic Way or Baltic Chain was a peaceful political demonstration that occurred on 23 August 1989. Approximately two million people joined their hands to form a human chain spanning 690 kilometres (430 mi) across the three Baltic states of Estonia, Latvia and Lithuania, which at the time were occupied and annexed by the USSR and had a combined population of approximately eight million. The central government in Moscow considered the three Baltic countries constituent republics of the Soviet Union.

A human chain is a form of demonstration in which people link arms or hands as a show of political solidarity.
