Margaret of Ravensberg

Margaret of Ravensberg (c. 1320–1389) was the daughter of Count Otto IV of Ravensberg and Margaret of Berg-Windeck. When her uncle Bernard, the last male count, died without issue in 1346, she inherited Ravensberg; two years later the death of her maternal uncle Adolf IX of Berg brought her the County of Berg as well.

Through her marriage to Gerhard VI of Jülich, both counties passed to the House of Jülich. She was the mother of William, the first Duke of Berg, and died in February 1389.
