Henry of Isenburg-Kempenich was the co-Lord of Isenburg-Kempenich in 1367, ruling jointly with his brothers Theodoric VI, John, and Henry. Henry was the youngest son of Simon II. After his death in 1367, Simon and his brothers became the co-rulers of Kempenich despite an agreement in 1345 whereby Kempenich was declared indivisible. Already in 1367 the brothers built a tomb for their father and sent their mother to the Abbey of Laach. Henry died in 1367.
