Maturinus Veyssière La Croze (4 December 1661, Nantes – 21 May 1739) was in his early years a learned French Benedictine historian and orientalist.

Later, as a Protestant convert, he became royal librarian and professor of the University of Berlin[1] Armenologist.

He studied theology in Le Mans and by 1682 he was a Benedictine at the Abbey of Saint-Germain-des-Prés in Paris.

Besides French, he spoke Latin, German, Armenian, and some Semitic and Slavic languages.

His works include Vindiciae veterum scriptorum contra J. Hardunium' (1708), the Histoire du christianisme des Indes (1724), Histoire du Christianisme d'Ethiopie et d'Arménie (1739),[2] and a Coptic-Latin dictionary.
