William Tolley, 42, was on the roof of an apartment building fighting a fire that started on the second floor when he fell, Fire Commissioner Daniel Nigro shared.
"A man dedicated to protecting others gave his life for this city," said democratic Mayor Bill de Blasio. "Today he made the ultimate sacrifice."
Tolley was rushed to a hospital and later died, and three others suffered minor injuries from the fire.
The FDNY announced Tolley's passing on Facebook.
"It is with deep regret that FDNY announces the line of duty death of Firefighter William N. Tolley," the post read. "Firefighter Tolley was critically injured while fighting a 2-alarm fire in Queens. He is the 1147th member of the Department to make the Supreme Sacrifice while serving our city."
Tolley is survived by his wife, Marie, and daughter, Isabella.
