Gerhard III, Count of Hoya

Gerhard III of Hoya (died 1383) ruled the County of Hoya from 1324, first jointly with his brother John after their father Otto II died. In 1345 the brothers divided the county, Gerhard taking the Lower County around Hoya and John the Upper County around Nienburg.

His long reign was spent in feuds: he fought the Hoya Feud of 1351–1359 against Bremen, and in 1370 joined Welf duke Magnus II in the Lüneburg War of Succession. He died in 1383.
