Albert van Ouwater (c. 1410/1415 – 1475) was one of the earliest artists of Early Netherlandish painting working in the Northern Netherlands, as opposed to Flanders in the South of the region.
He was probably born in Oudewater, and is mentioned by Karel van Mander (1604) as a reputable painter at the time in which he lived.
Van Ouwater seems to have been a contemporary of Dirk Bouts in mid-15th-century Haarlem, and Geertgen tot Sint Jans may have been his pupil.
This is the only widely accepted attribution to Van Ouwater, although many scholars also credit him with the small, fragmentary Head of a Donor in the Metropolitan Museum of Art in New York.
Less convincingly, Albert Châtelet adds a pair of altar wings with St. John the Baptist and St. Michael (both in the Capilla Real, Granada) to Van Ouwater's œuvre.
