The 1968 Red Square demonstration (Russian: Демонстра́ция 25 а́вгуста 1968 го́да) took place in Moscow on 25 August 1968. It was a protest by eight demonstrators against the invasion of Czechoslovakia on the night of 20–21 August 1968 by the Soviet Union and its Warsaw Pact allies, crushing the Prague Spring, the challenge to centralised planning and censorship by communist leader Alexander Dubček.

The protest took place at the Lobnoye Mesto (Place of Proclamation) on Red Square next to the Kremlin, to avoid any accusation of a violation of public order. It was a nonviolent, sit-down demonstration. However, all but one of the protestors was quickly and roughly arrested by police and plainclothes KGB men.
