Herman I, Count of Henneberg

Herman I, Count of Henneberg (1224 – 18 December 1290) was the son of Count Poppo VII of Henneberg and his wife, Jutta of Thuringia (born: 1184; died: 6 August 1235 in Schleusingen), the eldest daughter of Landgrave Herman I of Thuringia.

Margrave Henry III of Meissen was Herman's half-brother from his mother's side.

Herman supported the election of his uncle Henry Raspe as anti-king of the Germans.

Herman founded the "new lordship" around Coburg and Eisenburg, which was inherited by the House of Wettin via his grand-niece Catherine of Henneberg.

In 1249, Herman married Margaret (died: 26 March 1276), the sister of Count William II of Holland and King of the Germans.
