Odette Bancilhon (born 22 September 1908 – 1998) was a French astronomer.
She is known for her work during the 1930s and 1940s at the Algiers Observatory, where she discovered 1333 Cevenola, a stony Eunomian asteroid from the main-belt.
All of her publications are signed O.
Bancilhon, a practice of her profession at that time.
She later married her colleague Alfred Schmitt in the 1940s, and was known professionally as O.
Schmitt-Bancilhon.
The main-belt asteroid 1713 Bancilhon, discovered by colleague Louis Boyer in 1951, was named in her honor.
