Henry Alexander Scammell Dearborn (March 3, 1783 – July 29, 1851) was an American soldier, lawyer, author, and statesman.

After the war, he was elected captain of the Ancient and Honorable Artillery Company of Massachusetts in 1816.

In 1848, while he was Mayor of Roxbury, Dearborn designed and founded the Forest Hills Cemetery.

As President General he proposed changes in the Society's membership rules to allow for descendants of other than original members to join.

The Native American Party, a precursor to the Know Nothings, which had split from the Whig Party in 1845, met in September 1847 in Philadelphia, where they nominated Zachary Taylor for president while Dearborn was selected as his running mate.

Dearborn died on July 29, 1851, at the age of 68 in Portland, Maine, and is interred in Forest Hills Cemetery in Jamaica Plain, Massachusetts.
