Maura Tombelli (born 1952 in Montelupo Fiorentino) is an Italian amateur astronomer who began her training in astronomy as an observer of variable stars. She is a prolific discoverer of almost 200 minor planets, including the main-belt asteroid 7794 Sanvito, and a member of the American Association of Variable Star Observers.
She is known as the only Italian female astrometrist. Together with Italian astronomers Ulisse Munari and Giuseppe Forti, she initiated a five-year survey of minor planets at Asiago Astrophysical Observatory in 1994. She also shared a lot of observing with the discoverers, especially the follow-up of near-Earth objects (NEOs), and she contributed to the discovery of 15817 Lucianotesi, the first NEO found from Italy. She is currently involved in a project to build a new observatory (Osservatorio di Montelupo) near the town of Montelupo, where she lives.
The main-belt asteroid 9904 Mauratombelli, discovered by Italian astronomers Andrea Boattini and Luciano Tesi in 1997, is named in her honour.
