David Hoadley (April 29, 1774 – 1839) was an American architect who worked in New Haven and Middlesex counties in Connecticut.

Born in Waterbury, Connecticut, the son of Lemuel and Urania (Mallory) Hoadley, he began as a carpenter and builder.

He built many houses in New Haven, most of which are no longer standing, as well as the Tontine Hotel, now the site of the federal courthouse.

While Hoadley had no formal schooling and is dismissed as merely a “builder”[4] by some, others point to his genius in the use of wood for classical detail and his unsurpassed buildings, particularly the North Church.
