George Ellery Hale (June 29, 1868 – February 21, 1938) was an American astronomer.

As an undergraduate at MIT, he invented the spectroheliograph.

He helped found a number of observatories, including Yerkes Observatory and Mount Wilson Observatory. He hired and encouraged Harlow Shapley and Edwin Hubble and did a great deal of fundraising, planning, organizing and promotion of astronomical institutions, societies and journals. The Hale Telescope at Palomar Observatory is named after him.

He won the Henry Draper Medal in 1904, the Gold Medal of the Royal Astronomical Society in 1904, the Bruce Medal in 1916, the Copley Medal in 1932.

The asteroid 1024 Hale is named after him, as are Hale crater on the Moon and a crater on Mars.
