The Foundry Painter was an ancient Greek Attic red-figure vase painter of the Late Archaic period. His real name is unknown; the conventional name is derived from his most famous work, the Berlin Foundry Cup.
Together with a number of other notable vase painters, such as the Briseis Painter or the Dokimasia Painter, the Foundry Painter was active in the workshop of one of the most important Late Archaic red-figure vase painters, the Brygos Painter. He was less productive than his master, but artistically nearly as talented. His style and subject range are very similar to those of the Brygos Painter, who seems to have had a strong influence on all his collaborators in those regards. Nonetheless, the Foundry Painter's style differs in certain details; John Beazley judged his works as powerful, sometimes even crude.
In contrast to his contemporaries, his figures seem heavier, their faces more schematic. His figures are well-observed, and sometimes depicted not without humour. Such figures as foolish lovers, rotund hetairai and confounded revellers occur. He also attempted to depict body hair and to stress musculature.
