Georg Friedrich, Margrave of Baden-Durlach (d. 1638)
George Frederick of Baden-Durlach (30 January 1573 – 24 September 1638) was Margrave of Baden-Durlach from 1604 until his abdication in 1622. He also ruled Baden-Baden.

He was the third son of margrave Charles II of Baden-Durlach and his second wife, Anna of Veldenz. He was the youngest of eight children and was only four years old when his father died.

He succeeded his brother Ernest Frederick as margrave in 1604. He also continued his brother's occupation of Baden-Baden. George Frederick was a prominent member of the Protestant Union.

He raised an army of 12,000 men at the beginning of the Thirty Years' War in 1618. When Catholic League forces under General Tilly approached Baden in 1622 (Palatinate campaign), he marched against them, but came too late for the Battle of Mingolsheim. Setting off to pursue the retreating Catholics, he was defeated at the Battle of Wimpfen, and his army was destroyed, a few days later.

In 1627 he joined the Danish army.

He died at Strasbourg in 1638.
