John Mulrooney, a beloved stand-up comedian, radio personality, and late-night television veteran, has died suddenly at the age of 67. According to the Albany Times Union, he passed away at his home in Coxsackie, New York, on December 29, 2025. The news came as a shock to friends, fans, and colleagues, many of whom said he had been actively planning future projects and performances.
Born and raised in Brooklyn, Mulrooney rose during the hard-edged comedy boom of the 1980s, performing at legendary clubs before becoming a familiar face on television. He appeared on numerous comedy shows and briefly stepped in as host of The Late Show in 1987 after Joan Rivers’ departure. His fearless, loose style made him a standout in an era crowded with talent.
After returning east, Mulrooney reinvented himself as a radio star, co-hosting popular morning shows that reached listeners across New York and beyond. Even later in life, he never left the stage, continuing to perform stand-up well into 2025. Comedy, friends said, wasn’t just his job—it was his identity.
Beyond entertainment, Mulrooney also served as a police officer for over a decade, often using comedy to support charity events for first responders. Remembered for his loyalty, generosity, and ability to light up a room, he leaves behind a legacy defined by laughter, service, and deep personal connections.
