Marcelle Lalou (1890–1967) was a 20th-century French Tibetologist.
Her major contribution to Tibetology was the cataloging of the entire Pelliot collection of Old Tibetan manuscripts from Dunhuang at the Bibliothèque nationale de France.
In addition to her cataloging work, she wrote articles on various aspects of Old Tibet, and she published a Tibetan textbook.
Some of her most notable students include Rolf A.
Stein and J.
W.
de Jong.
Lalou was born August 23, 1890 at Meudon-Bellevue between Paris and Versailles.
She was interested in art from an early age, and she painted and drew for pleasure her whole life.
Her studies began in Art History, and many of her early publications are devoted to Art-historical themes.
Lalou volunteered as a nurse in the first world war.
