Laszlo Toth (Hungarian: Tóth László; born 1 July 1938) is a Hungarian-born Australian geologist.

As his English was poor and his geology diploma was not recognised, he initially worked at a soap factory.

[1] On 21 May 1972, at 33 years of age (the traditional age of Jesus at his death) on the Feast of Pentecost, Toth, wielding a geologist's hammer and shouting "I am Jesus Christ—risen from the dead",[1][3][4] attacked Michelangelo's Pietà statue in St. Peter's Basilica, Vatican City.

With fifteen blows, he removed Mary's arm at the elbow, knocked off a chunk of her nose, and chipped one of her eyelids.

[4] He was subdued by bystanders, including American sculptor Bob Cassilly, who struck Toth several times before pulling him away from the Pietà.
