Martí Joan de Galba (d. 1490) was co-author of the famous Catalan epic Tirant lo Blanc, which he helped finish during and after the death of his friend, the main author of the work, Joanot Martorell. David H. Rosenthal, one of the two translators of the work into English, notes that among Joan de Galba's stylistic contributions to the work are his precision with place-names and his reliance on John Mandeville's Travels.
