The attempted coup d'état of March 1935 (Greek: Κίνημα του 1935) was a Venizelist revolt against the People's Party government of Panagis Tsaldaris, which was suspected of pro-royalist tendencies.

The coup was headed by Nikolaos Plastiras, and broke out on 1 March 1935, but failed to establish itself in Athens and most of mainland Greece. The government quickly reacted, and loyal forces under the leadership of General Georgios Kondylis put the revolt down by March 11, when Venizelos himself was forced to flee Greece. In the coup's aftermath, a military tribunal was set up, which purged the Armed Forces of Venizelist and Republican officers, and ordered the execution of two prominent Venizelist generals, Anastasios Papoulas and Miltiadis Koimisis, and major Stamatis Volanis on April 24. Venizelos and Plastiras likewise were condemned to death in absentia. In the political sphere, the failure of the revolt marked the triumph of anti-Venizelist forces, and actually quickened the collapse of the fragile Second Hellenic Republic. Its final death blow was given in October, when the Armed Forces overthrew the government in a coup (due to their consideration of Tsaldari's stance towards the immediate restoration of monarchy as indecisive, and due to personal motives of Kondylis and his political and military circle), and Kondylis declared himself regent for the restored monarchy.
