Otto II, Count of Hoya

Otto II (1271–1324) was count of Hoya from 1313, when he succeeded his childless elder brother Gerhard II, until his death. A younger son of Count Henry II, he married Ermengard of Holstein and had four children.

During his short reign he allied with neighboring princes, including the dukes of Brunswick-Lüneburg and the archbishopric of Bremen. He had already agreed that his sons Gerhard and John should divide the county, which they did in 1345.
