Vladimir Konstantinovich Bukovsky (Russian: Влади́мир Константи́нович Буко́вский; 30 December 1942 – 27 October 2019) was a Russian-born British human rights activist and writer. From the late 1950s to the mid-1970s, he was a prominent figure in the Soviet dissident movement, well known at home and abroad.

He spent a total of twelve years in the psychiatric prison-hospitals, labour camps, and prisons of the Soviet Union during Brezhnev rule. After being expelled from the Soviet Union in late 1976, Bukovsky remained in vocal opposition to the Soviet system and the shortcomings of its successor regimes in Russia. An activist, a writer, and a neurophysiologist, he is celebrated for his part in the campaign to expose and halt the political abuse of psychiatry in the Soviet Union.
