Alexander Keirincx (Antwerp, 23 January 1600-Amsterdam, 1652) was a Flemish Baroque painter who spent his later career in the Dutch Republic. He became a master in Antwerp's guild of St. Luke in 1619, and like his teacher Abraham Govaerts he initially specialized in small cabinet-sized forest landscapes in the manner of Jan Brueghel the Elder and Gillis van Coninxloo. Also like Govaerts, Keirincx's early works typically show diminutive history, mythological or biblical subjects within a Mannerist three-color universal landscape bracketed by repoussoir trees. However, during the 1620s his landscapes become increasingly natural. He lived in Utrecht and Amsterdam from 1628 until the end of his career, and made trips to England to decorate palaces for Charles I. The figures in his works were usually painted by collaborators such as Cornelis Poelenburg. Keirincx worked primarily as an art dealer later in life.
