Thomas Charles Fulp (born April 30, 1978) is an American programmer known for creating the website Newgrounds and co-founding the video game company The Behemoth.

Fulp has been credited with "changing the landscape of the Internet forever" by kickstarting the browser game scene in the late 1990s, both with the releases of his own advanced Flash games and the launch of the Newgrounds Portal, which made Newgrounds one of the first sites that allowed creators to easily share their creations with a large online audience. Fulp is also notable for his browser game preservation work.
