Robert (1319 or early winter 1326 – 10 September 1364), of the Capetian House of Anjou, was prince of Taranto (1331–1346), lord of the Kingdom of Albania (1331–1332), prince of Achaea (1332–1346), and claimant to the Latin Empire (1343 or 1346 – 1364) as Robert II.
He was the oldest surviving son of Prince Philip I of Taranto (1278–1331) and Catherine of Valois-Courtenay.
In 1332, an exchange occurred in which his uncle John, Duke of Durazzo arranged to surrender Achaea to him in exchange for Robert's rights to the Kingdom of Albania and a loan of 5,000 ounces of gold raised upon Niccolò Acciaioli. Robert then officially became Prince of Achaea. Because of his youth, authority was effectively exercised by his mother, Catherine of Valois, until her death in 1346. At that point, Robert inherited the throne of the Latin Empire and was recognised as emperor by the Latin states of Greece. His actual power, such as it was, remained based upon his authority as prince of Achaea. In Naples, on 9 September 1347, Robert married Marie of Bourbon, the daughter of Duke Louis I of Bourbon, constable of Cyprus, but the marriage was childless. He died on 10 September 1364 in Naples and was buried there. After he died, his widow attempted to keep the principality for herself and her son from her previous marriage. However, Robert's younger brother Philip II succeeded.
