Matthias Grunewald (Matthias, Mathias, or Mathis Gothardt-Neithardt), German painter.
Documents place him in Seligenstadt from 1501 to 1521 as the owner of a workshop.
By 1509 he had become court painter to the archbishop of Mainz, and by the second decade of the century he was also accepting commissions in Isenheim and Aschaffenburg.
