Frederick III of Nuremberg (c. 1220–14 August 1297, Cadolzburg), Burgrave of Nuremberg from the House of Hohenzollern, was the eldest son of Conrad I of Nuremberg and Adelheid of Frontenhausen.

He owned the possessions of Hohenzollern on the west of Nuremberg around the castle Cadolzburg. In 1248 he received from the Counts of Andech the region of Bayreuth by so-called Meran's inheritance. However, this led to a quarrel with other noble houses who also has the claims on this lands. After the death of Konrad I in 1261 he became Burgrave of Nuremberg and tried to eliminate the Frankish power in the Main region. That resulted in the violent opposition of the bishops of Würzburg and Bamberg.

In 1273 he gave his deciding vote for his friend Rudolf of Habsburg on the election of the king of the Romans. As a reward the King confirmed his position as a Burgrave and granted the rank of a Prince-Elector. Thus Frederick was entrusted with the royal district court of Franconia, took part in the imperial war against the outlawed Otakar II of Bohemia and also joined in the struggle in the Battle of Dürnkrut and Jedenspeigen in 1278. More particularly, he had a territorial quarrel with Bohemia about the land around Eger. In this time into the possession of the House of Hohenzollern came Wunsiedel, Erlangen and Arzberg.

1. Johann, murdered near Nuremberg ca. 1262.

   2. bef. 13 March 1285 Gottfried II of Hohenlohe.

He married a second time. On the 10 April 1280, Helene of Saxony, daughter of Albert II, Duke of Saxony and Helene of Braunschweig, became his wife. They had the following children:

1. John I of Nuremberg (ca. 1279–1300).
