272 Antonia is a main belt asteroid that was discovered by French astronomer Auguste Charlois on February 4, 1888 in Nice.

Photometric observations of this asteroid made during 2008 at the Organ Mesa Observatory in Las Cruces, New Mexico gave a light curve with a short rotation period of 3.8548 ± 0.0001 hours and a brightness variation of 0.43 ± 0.04 in magnitude.[2]
