John Mulrooney, widely celebrated as a talented radio host and sharp stand-up comedian, passed away unexpectedly at 67 in late December 2025 at his home in Coxsackie, New York. His death shocked friends, colleagues, and fans who had followed his career for decades. Reported by Albany Times Union, he was active and making plans just weeks before his passing, highlighting how sudden his loss was.
Born in Brooklyn, Mulrooney rose from the competitive 1980s comedy scene, performing at clubs like Dangerfield’s and Sheepshead Bay before moving to prominent stages such as The Improv and The Laugh Factory. His wit and fearless style earned him TV appearances and a national profile. In 1987, he briefly hosted The Late Show, a milestone that cemented his place in late-night history.
His career spanned beyond TV and stand-up. He appeared on various entertainment programs, competed on game shows, and created a sitcom. Later, he reinvented himself as a prominent radio host, co-hosting popular morning shows on the East Coast and earning praise for his chemistry and candid humor. Despite focusing on radio, he continued performing stand-up into 2025, often at festivals and events supporting first responders.

Beyond entertainment, he served as a police officer, balancing public service with comedy. Remembered for his generosity, loyalty, and heart, John Mulrooney’s legacy is rooted in the laughter, reinvention, and authenticity he shared with the world.
