Hieronymus Bosch (; ; born Jheronimus van Aken ; – 9 August 1516) was a Dutch painter from Brabant. He is one of the most notable representatives of the Early Netherlandish painting school. His work, generally oil on oak wood, mainly contains fantastic illustrations of religious concepts and narratives.

Within his lifetime, his work was collected in the Netherlands, Austria, and Spain, and widely copied, especially his macabre and nightmarish depictions of hell. Little is known of Bosch's life, though there are some records. He spent most of it in the town of 's-Hertogenbosch, where he was born in his grandfather's house. The roots of his forefathers are in Nijmegen and Aachen (reflected in his surname, Van Aken).

His original, fantastical style cast a wide influence on northern art of the 16th century; Pieter Bruegel the Elder was his best-known follower. Today, Bosch is seen as a highly individualistic artist who offered profound insights into humanity's desires and deepest fears. Attribution of his work has been especially difficult; today only about 25 paintings are confidently identified as his, along with eight drawings. About another half-dozen paintings are confidently attributed to his workshop.

His most acclaimed works consist of three triptych altarpieces, particularly The Garden of Earthly Delights.
