Jason Thomas (born July 4, 1974) is a United States Marine who located and rescued people in the aftermath of collapse of the World Trade Center in New York City after the September 11 attacks in 2001.

With fellow U.S. Marine David Karnes, he helped find a pair of Port Authority Police officers buried in the rubble of the World Trade Center.

The 27-year-old Thomas, having left active duty in August 2001, quickly put on his Marine uniform (camouflage utilities), sped to Manhattan, and had just parked his car when the North Tower of the World Trade Center collapsed.

They met a retired EMT, Chuck Sereika, who crawled down into the 50-foot-deep hole where the 2 Port Authority police officers (Will Jimeno and John McLoughlin) were trapped.

A 3rd Port Authority police officer, Dominick Pezzulo, was trapped with Will and John but was mortally wounded by debris from the WTC 7 building collapse while trying to extricate Will from the rubble.

On September 2, 2013, Channel 4 detailed Thomas' involvement in the rescue operation following the collapse of the towers in the UK broadcast The Lost Hero of 9/11.
