Count Friedrich IV of Zollern (c. 1188 – c. 1255), also known as Burgrave Friedrich II of Nuremberg, was Burgrave of Nuremberg from 1204 to 1218 and Count of Zollern from 1218 until his death.
After his father's death, he was appointed as his successor as Burgrave of Nuremberg.
In 1218, Friedrich and his older brother Conrad I divided their inheritance: Conrad received the Franconian possessions and became Burgrave of Nuremberg; Friedrich received the ancestral County of Zollern.
He is considered the founder of the Swabian line of the House of Hohenzollern.
