Ithiel Town was an American architect and civil engineer. One of the first generation of professional architects in the United States, Town made significant contributions to American architecture in the first half of the 19th century. His work, in the Federal and revivalist Greek and Gothic revival architectural styles, was influential and widely copied.

Federal-style architecture is the name for the classical architecture built in the United States following the American Revolution between c.  1780 and 1830, and particularly from 1785 to 1815, which was influenced heavily by the works of Andrea Palladio with several innovations on Palladian architecture by Thomas Jefferson and his contemporaries. Jefferson's Monticello estate and several federal government buildings, including the White House, are among the most prominent examples of buildings constructed in Federal style.
