Simon I of Bentheim

Simon I (c. 1310–1344) was Count of Bentheim from 1333 until his death. The eldest son of Count John II and Mechthild of Lippe, he succeeded on his father's death in 1333.

He allied with Tecklenburg and waged feuds against the Bishopric of Münster. He married Catherine, daughter of Count Ludolf VI of Steinfurt, but had no children, so on his death in 1344 the county passed to his younger brother Otto III.
