Asa Dodge Smith (September 21, 1804 – August 16, 1877) was an American Presbyterian preacher who served as the 7th president of Dartmouth College from 1863 until his death in 1877.

After the forced resignation of Nathan Lord in 1863 over his support for slavery, the Trustees wanted a more conservative president to take his place.

As a preacher for 29 years at the 14th Street Presbyterian Church in New York City, Asa Dodge had developed a reputation as a religious man with abolitionist beliefs.

Smith's presidency was a period of great growth for the College, including the establishment of two new schools within Dartmouth.

Over the course of his presidency, enrollment at the College was more than doubled, the number of scholarships increased from 42 to 103, and Dartmouth benefited from several important bequests.
