- Pedro de Araújo was a Portuguese organist and composer who worked with the Roman Catholic Archdiocese of Braga, northern Portugal. He was singing master at the Conciliar Seminary of St. Peter and St. Paul in Braga between 1663 and 1668, and second organist at Braga Cathedral until 1665. Like Juan Cabanilles, he was one of the last representatives of the traditional Iberian organ style.

- Araújo's organ works are characterized by their intricate ornamentation, expressive harmonies, and rhythmic vitality. They evoke a sense of spiritual grandeur, often being performed in sacred settings. His compositions, such as the Tento and the Batalha, continue to be celebrated for their beauty and historical significance, serving as a window into the musical treasures of 17th-century Portugal.
