Margaret of Ravensberg (c. 1320 – 13 February 1389) was the daughter and heiress of Otto IV, Count of Ravensberg and Margaret of Berg-Windeck.
[1] Margaret's father, Otto, had no sons, so at his death in 1328, the County of Ravensberg went to his younger brother Bernhard.
However, when Bernhard died in 1346 without issue, Margaret became the heiress of Ravensberg, her elder sister and only sibling, Hedwig, having died in 1336.
As a result of her marriage to Gerhard VI of Jülich, Berg and Ravensberg passed into the house of Jülich where they remained until 1511 when they passed into the house of Cleves.
Margaret married Gerhard VI of Jülich.
