'''83 Beatrix''' is a fairly large [[asteroid]] [[orbit]]ing in the inner part of the [[Asteroid belt|main asteroid belt]]. It was discovered by [[Annibale de Gasparis]] on April 26, 1865. It was his last asteroid discovery. A diameter of at least {{convert|68|km|mi}} was determined from the Beatrician [[star|stellar]] [[occultation]] observed on June 15, 1983. It is named for [[Beatrice Portinari]],<ref>{{cite book|title=(83) Beatrix In: Dictionary of Minor Planet Names |publisher=Springer |date=2003 |isbn=978-3-540-29925-7 |doi=10.1007/978-3-540-29925-7_84}}</ref> beloved of [[Dante Alighieri]] and immortalized by him in ''[[La Vita Nuova]]'' and ''[[The Divine Comedy]]''.

On February 16, 2001, an occultation of a magnitude +9.09 star by this asteroid was observed from three locations. The resulting chords matched an elliptical profile with a [[mean radius]] of 35.9&nbsp;km. The observers noted some dimming and flickering at the beginning of the event, which may indicate the star was binary or the asteroid has an irregular shape. Previous occultations had been observed in 1983 and 1990, which produced a much larger size estimate of 81.4&nbsp;km.<ref name=Povenmire2001/>
