The Master of the Legend of Saint Catherine (or the Master of the Saint Catherine Legend) is the Notname for an unknown late 15th century Early Netherlandish painter. He was named after a painting with Scenes from the Legend of Saint Catherine, now kept in the Royal Museums of Fine Arts of Belgium. He was active between c. 1470 and c. 1500, probably around Brussels.
In the 19th century, his works, like many Early Netherlandish paintings, were attributed to Jan Van Eyck or Hans Memling. At the 1902 Exposition des primitifs flamands à Bruges, the Mass of Saint Gregory panels (now in the Metropolitan Museum) were attributed to an unknown follower of Rogier Van der Weyden, placing the artist more in the Brussels' school of artists than the earlier attributions. Multiple works were first attributed to this artist by Max Jacob Friedländer.
It has been speculated that the Master may be the Brussels master Pieter van der Weyden, son of Rogier van der Weyden. No works by Pieter van der Weyden are known, even though he was clearly an important painter in Brussels in the late 15th century.
Works which have been said to be by the workshop of the Master, or in his circle, or otherwise related to his work and style, include:
