Henry II, Duke of Brunswick-Lüneburg, (before 1296 – after 1351), also called de Graecia ("of Greece"), was the eldest son of Henry I, Duke of Brunswick-Lüneburg and Agnes of Meissen. On their father's death in 1322, his sons agreed to rule the Principality of Grubenhagen jointly; but they finally divided up the territory, and Henry did not receive a part, and instead took over the administration of the brothers' joint property.
