Maria Montoya Martinez (1887, San Ildefonso Pueblo, New Mexico – July 20, 1980, San Ildefonso Pueblo) was a Native American artist who created internationally known pottery. Martinez (born Maria Poveka Montoya), her husband Julian, and other family members, including her son Popovi Da, examined traditional Pueblo pottery styles and techniques to create pieces which reflect the Pueblo people's legacy of fine artwork and crafts. The works of Maria Martinez, and especially her black ware pottery, survive in many museums, including the Smithsonian, the Metropolitan Museum of Art, the Denver Art Museum, and more. The Penn Museum in Philadelphia holds eight vessels – three plates and five jars – signed either "Marie" or "Marie & Julian".
