Juan Martínez de Ripalda (1594 at Pamplona, Navarre – 26 April 1648 at Madrid) was a Spanish Jesuit theologian.
Later he was named censor to the Spanish Inquisition and confessor of Gaspar de Guzmán, Count-Duke of Olivares, the favorite of Philip IV of Spain, whom he followed when he was exiled from Madrid.
Mentally he qualifies him as subtle in argument, sound in opinion, keen-edged and clear in expression, and well-versed in Augustine of Hippo and Thomas Aquinas.
According to Paul Drews, no Jesuit ever occupied this chair in the University of Salamanca with more honor than he, and Hurter places him, with Lugo, first among the contemporary theologians of Spain, and perhaps of all Europe.
"Expositio brevis litterae Magistri Sententiarum" (Salamanca, 1635), praised by the Calvinist Voet.
