How many firefighters died on 9/11?

343 FDNY firefighters, plus one New York Fire patrolman, were killed in the terrorist attacks, along with dozens of other public safety personnel

The September 11, 2001, terrorist attacks claimed the lives of 2,977 people, including 343 Fire Department of New York City (FDNY) firefighters and one New York Fire patrolman.

The incident marks the largest loss of life of any emergency response agency in history, according to the National Commission on Terrorist Attacks upon the United States.

The 343 FDNY firefighters killed in the September 11 attacks on the World Trade Center’s Twin Towers hailed from 75 firehouses across the city.

FDNY’s Chief of Department, Pete Ganci, was among the members killed, as was Chaplain Mychal Judge. Several other top commanders and chiefs from the FDNY were also killed in the collapse of the Twin Towers.

The 9/11 attack was such a monumental loss of life for the FDNY that it forged and strengthened a relationship with the National Fallen Firefighters Foundation, which still supports the department’s members to this day. NFFF Executive Director Ron Siarnicki details the Foundations early involvement in supporting FDNY in the days and weeks after 9/11 in “Rising from Ground Zero,” a digital edition focused on the New York City response and recovery efforts. Learn more about how the NFFF’s mission shifted post-9/11 and the ongoing support the foundation offers FDNY.

The New York Fire Patrolman killed on 9/11 was Keith Roma. While not an FDNY firefighter and therefore not included in the commonly referenced 343 figure, Roma was a firefighter, and some believe the 343 designation should be updated to 344 to honor Roma’s service.

Official statistics show that 343 firefighters lost their lives on that day, but there were really 344
