George (17 November 1582, Celle – 2 April 1641, Hildesheim) was duke of Brunswick-Lüneburg.
He was son to William, Duke of Brunswick-Lüneburg (1535 – 1592) and Dorothea of Denmark (1546 – 1617). His mother was daughter to Christian III of Denmark and Dorothea of Saxe-Lauenburg. She acted as a regent during the early years of his reign, keeping power from the councillors who had mismanaged the estates during his father's fits of insanity.
In the 1635 division of the territories of the House of Welf, he received the principalities of Calenberg and Göttingen. He was the first duke to move his residence to Hanover. After his death, he was succeeded by his son Christian Louis.
