The Rev. Ezra Stiles (November 29, 1727 - May 12, 1795) was a Congregational clergyman, and President of Yale College from 1778 to 1795. He was also a dedicated supporter of the American Revolutionary cause and an avid amateur scientist who corresponded with Thomas Jefferson and Benjamin Franklin about scientific discoveries.

He married twice and had eight children. He owned at least one slave, named Newport, whom he freed on June 9, 1778.

Ezra Stiles is also the name of a residential college at Yale University. It is among the newest of the university's 12 residential colleges, and is well known for its successes in acquiring the Gimbel and the Tyng Cup. Ezra Stiles is noted architecturally for its lack of right angles between walls. The building was designed by architect Eero Saarinen. Its mascot is the moose; this arose from the installation of a stuffed moose's head, in honor of former college master and Yale president A. Bartlett Giamatti, which is currently decomposing away in the Ezra Stiles Dining Hall. Ezra Stiles has a twin sister college named Morse College located adjacent to it, which is architecturally similar.
