William Michael Feehan (September 29, 1929 – September 11, 2001) was a member of the Fire Department of New York who died during the collapse of the World Trade Center during the September 11 attacks.

Early life William Feehan was born September 29, 1929, in Long Island City, Queens, and grew up in Jackson Heights. during which he was decorated with the Combat Infantry Badge, Korean Service Medal, UN Service Medal and National Defense Service Medal. He was promoted to Lieutenant in 1964 and eventually to Chief of Department in 1991. In 1992, he was appointed Deputy Fire Commissioner. Upon the resignation of Fire Commissioner Carlos M. Rivera, he briefly served as Acting Fire Commissioner through the end of Mayor David N. Dinkins administration from August 31, 1993, until December 31, 1993.

After then-incoming Mayor Rudolph W. Giuliani picked Howard Safir to become Fire Commissioner of the City of New York, Feehan returned to his previous position of First Deputy Fire Commissioner of the City of New York. Although high-ranking members of the FDNY and other city departments ordinarily are asked to step aside for incoming mayors to make their own appointments, according to an FDNY spokesman, this was not requested of Feehan, because he was so knowledgeable that he "was thought to know the location of every fire hydrant in the city." Feehan served in that position, the second-highest position in the department, until his death.
