Maria van Beckum (before 1510 – 13 November 1544) was a Dutch noblewoman and Anabaptist executed for heresy.
When their mother died, their father remarried Beatrix van de Hoeve, who threw Maria out of the house for becoming a follower of David Joris.
In 1542, the Anabaptists were declared heretics in the Netherlands, and some time after that Maria was taken in by her brother.
Their case attracted a lot of attention and Maria is remembered in the Martyr's Mirror by Thieleman J. van Braght.
