Duke of Lafões (in Portuguese Duque de Lafões) was a Portuguese title of nobility created under the decree of February 17, 1718, of King John V of Portugal and granted to his nephew, Dom Pedro Henrique de Bragança, son of the Infante Miguel de Bragança, an illegitimate son of King Peter II of Portugal and Anne Armande Pastre de Verger, though Pedro's mother, Luisa Casimira de Sousa Nassau e Ligne was the first to use this title.The title was later passed on to his brother, João Carlos de Bragança e Ligne de Sousa Tavares Mascarenhas da Silva, the most famous Duke of this title.
Luísa Casimira de Sousa Nassau e Ligne, Duchess of Lafões (1694–1729), married to Infante Miguel of Braganza (natural son of king Peter II of Portugal), was the first to use this title. However, she is not included in the list of Dukes, once King John V's decree granted the title to Luísa's older son:
The House of Lafões descends from the marriage between Infante Miguel of Braganza (King Peter II's natural son) and Luísa-Casimira, 30th representative of the House of Sousa and 6th Countess of Miranda do Corvo.
