Andrew, Duke of Calabria (30 October 1327 – 18 September 1345) was the first husband of Joanna I of Naples, and a son of Charles I of Hungary and brother of Louis I of Hungary.

Background and engagement
Andrew was the second of three surviving sons of King Charles I of Hungary and his third wife, Elizabeth of Poland. He was betrothed in 1334 to his cousin Joanna, granddaughter and heir presumptive of King Robert of Naples; Andrew's father was a fraternal nephew of King Robert, making Andrew and Joanna both members of the Capetian House of Anjou.
Robert's claim to the throne was rather tenuous and did not follow primogeniture. Andrew's grandfather, Charles Martel of Anjou, had died young; therefore, the throne should have passed to Andrew's father. However, due to fears of impending invasion from Sicily, it was felt that a seven-year-old heir was too risky and would not be able to hold off invasions. The throne was offered to the next son of Charles II of Naples, Louis, but he refused on religious grounds, and it thus passed to Robert. To recompensate Andrew's father, Charles II decided to assign him the claim to Hungary.
When King Robert died in 1343, in his last will and testament, he formally bequeathed his kingdom to his granddaughter Joanna, making no mention of Andrew and thus denying him the right to reign along with Joanna.
