Frederick II (9 July 1857 – 9 August 1928) was the last sovereign Grand Duke of Baden, reigning from 1907 until the abolition of the German monarchies in 1918.

Frederick became the head of the House of Zähringen on 28 September 1907, after the death of his father Frederick I. He abdicated on 22 November 1918, amidst the tumults of the German Revolution of 1918–19 which resulted in the abolition of the Grand Duchy.

After his death in 1928, the headship of the house was transferred over to his grand uncle's grandson, thus being his second cousin who was the last Chancellor of Imperial Germany, Prince Maximilian of Baden.

As a student at the University of Heidelberg, Frederick was a member of the Suevia Corps, a student organization.

After the death of his cousin Carola of Vasa, he became the representative of the descent of the Kings of Sweden of the House of Holstein-Gottorp.

On 20 September 1885 in Schloss Hohenburg, he married Princess Hilda of Nassau, the only daughter of the exiled Duke Adolphe of Luxembourg. There was no surviving issue from the marriage.

He was à la suite the Royal Prussian Regiments Erstes Garde-Regiment zu Fuß (1st Guard Foot Regiment) and 1. Garde-Ulanen-Regiment and à la suite the Imperial 1st Seebataillon.

The state of Baden originated from the area of the Grand Duchy. In 1951/52, it became part of the new state of Baden-Württemberg.
