Giorgio Abetti (5 October 1882 – 24 August 1982) was an Italian solar astronomer.[1]

He was born in Padua, the son of noted astronomer Antonio Abetti. He was educated at the Universities of Padua and of Rome.[1]

He began his career at the Collegio Romano observatory in Rome as an assistant astronomer. In 1921 he succeeded his father as the director of the Osservatorio Astrofisico di Arcetri, and continued until 1957. Starting at the same time he was also a professor at the University of Florence, and continued in this capacity until 1957.[1]

Giorgio Abetti is noted for having led expeditions to observe solar eclipses to Siberia (1936) and Sudan (1952). He was also a visiting professor at the University of Cairo in 1948–49. He was the vice president of the International Astronomical Union in 1938, and received the Medaglia d'argento from the Italian Geographic Society (1915), the Premio reale from the Accademia dei Lincei (1925), and the Janssen medal (1937).[1]

In 1937, Abetti received the Prix Jules Janssen, the highest award of the Société astronomique de France, the French astronomical society.

The crater Abetti on the Moon and asteroid 2646 Abetti are named to honor both him and his father.
