The Bloc of Oppositions, also known as Trotsky's bloc and called by the Soviet press the Bloc of Rights and Trotskyites, was a political alliance created by oppositionists in the USSR and Leon Trotsky by the end of 1932. It was a secret organization to fight Stalinist repression in the Soviet Union.

The Bloc was accused in the Moscow Show Trials of having committed terrorist acts, while in reality that was a fabrication against the opposition. It was, in reality, merely a political, ephemeral alliance.
