9912 Donizetti is an S-type main belt asteroid. It orbits the Sun once every 4.11 years. It is associated with the Rafita family of asteroids.

Discovered on October 16, 1977 by Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld on photographic plates taken by Tom Gehrels with the Samuel Oschin telescope at the Palomar Observatory, it was given the provisional designation "2078 T-3". It was later renamed "Donizetti" after Italian composer Gaetano Donizetti.
