Redemptus of the Cross, born Tomás Rodrigues da Cunha, was a Portuguese Carmelite lay brother and diplomat who lived from 1598 to 1638. Originally a soldier serving in India, he joined the Discalced Carmelites in Goa in 1615. He later participated in a diplomatic mission to Aceh, accompanying Denis of the Nativity. During this mission, he was apprehended by Dutch authorities, where he faced torture and eventual execution for refusing to renounce his Catholic faith.
