Duke of Loulé is a Portuguese title that was originally granted to the family of Folque Mendoça de Moura Barreto.

The dukedom was created by a royal decree of King Luis I of Portugal, dated from October 3, 1862, to his grand-uncle Nuno José Severo de Mendoça Rolim de Moura Barreto, 2nd Marquis of Loulé and 9th Count of Vale de Reis. The new duke descended from earlier Portuguese monarchs and belonged to the highest nobility.

Duke Nuno served several times as Prime Minister of Portugal.

On December 5, 1827, Nuno of Loulé married Infanta Ana de Jesus Maria of Braganza and Bourbon, youngest daughter of King John VI of Portugal. She bore him five children, but died before he was elevated to ducal rank.

When the deposed King Manuel II of Portugal died in 1932, Constança Maria was the representative of the House of Loulé (4th Duchess of Loulé, if one counts all the subsequent heirs of the original duke, including those that never registered the ducal title as required by law during the monarchy).

The current representative is the infanta's great-great-great-grandson, Dom Pedro de Mendoça Rolim de Moura Barreto. He is styled 6th Duke of Loulé in D. Filipe de Loulé's work on the "House of Loulé". But he is the 4th duke according to Portugal's post-monarchic titular convention, which considers the title only properly renewed in 1992 for D. Pedro's father, the 3rd (or 5th) duke (who also registered the style of Dom, which the Loulés had not traditionally used, although entitled to do so). According to its 1998 Boletim Oficial, a request for the third renewal of the ducal title was submitted to the Conselho de Nobreza, headed by D. Duarte Pio, Duke of Bragança.
