Jean-Baptiste Cerlogne (6 March 1826 - 7 October 1910) was a poet-priest and scholar of the Valdôtain dialect of Franco-Provençal.
He is celebrated as a pioneer of Franco-Provençal grammar and lexicography, identifying a vocabulary for a set of dialects that had hitherto very largely been transmitted only orally.
He is also considered the principal poet of the Aosta Valley, where he lived for most of his life, being a Savoyard in his youth before becoming an Italian.
