Judith Jans Leyster (also Leijster; baptised July 28, 1609 – February 10, 1660) was a Dutch Golden Age painter of genre works, portraits, and still lifes. Her work was highly regarded by her contemporaries but largely forgotten after her death. Her entire oeuvre came to be attributed to Frans Hals or to her husband, Jan Miense Molenaer. In 1893, she was rediscovered and scholars began to attribute her works correctly.
Self-portrait by Judith Leyster is a Dutch Golden Age painting in oils now in the collection of the National Gallery of Art in Washington DC. It was offered in 1633 as a masterpiece to the Haarlem Guild of St. Luke. It was attributed for centuries to Frans Hals and was only properly attributed to Judith Leyster upon acquisition by the museum in 1949. The style is indeed comparable to that of Hals, Haarlem's most famous portraitist.
In 2016 a second self-portrait was found, dating from around 1653.
