Pietro Cascella (February 2, 1921 – May 18, 2008) was an Italian painter and sculptor.
Cascella was born at Pescara into a family of ceramics artists. In 1938 he moved to Rome where he frequented the Accademia di Belle Arti. In 1943 he took part in the Quadriennale di Roma painting exhibition and, in 1948, to the first post-World War II Biennale di Venezia.
He is noted for his Carrara marble sculptures and his paintings, which often hark back to impressionism and post-impressionism. He created monumental sculptures for locations as varied as the Auschwitz death camp and Silvio Berlusconi's underground mausoleum in his villa at Arcore.
Cascella lived in a medieval castle at Verrucola. He died at Pietrasanta in 2008.
