The King of Camelot was the male monarch of Camelot. Uther Pendragon became King of Camelot after he took over the kingdom (The Sorcerer's Shadow). After his death, he was succeeded by his son, Arthur Pendragon (The Wicked Day). Although not officially King, Helios was close to Morgana during her second reign, provided her with army and even took part in ruling Camelot, so he partially had a king's duties.
