Otto VII of Tecklenburg (died 1450) was Count of Tecklenburg from 1426 until his death.
Otto VII was the only son of Count Nicholas II of Tecklenburg and his wife Anna Elisabeth, a daughter of Count Frederick III of Moers. In 1426, he succeeded his father as Count of Tecklenburg. Like his father, he fought many feuds, in an attempt to win back some of the territories his father had lost. The attempt failed, and pushed his county deeper into debt. This accelerated the decline of the county.
He died in 1450, and was succeeded by his eldest son, Nicholas III.
Around 1428, he married Ermengarda of Hoya-Nienburg, the daughter of Count Eric I of Hoya. They had two children:
After Ermengarde's death, Otto VII married Aleidis, the daughter of Gottschak VIII of Plesse and had three more children:
