Family of the star, who appeared on Friends and HBO's Somebody, Somewhere, paid tribute as they said he would be "sorely missed".
Mike's co-star Bridget Everett broke the sad news on social media, writing: "With great sadness, the family of Michael G. Hagerty announced his death yesterday in Los Angeles.
“A beloved character actor, his love of his hometown of Chicago and his family were the cornerstones of his life.
“Mike, a devoted husband, is survived by his wife Mary Kathryn, his sister Mary Ann Hagerty [and] her wife Kathleen O’Rourke, and their daughter Meg.
“He will be sorely missed.”
Mike was best known for his recurring role as building superintendent Mr Treeger from 1995 until 2001.

Upset fans flocked to Twitter to share their sadness over the news, with one writing: "RIP Mike Hagerty. Funny, sweet and a total pro. Thanks for the decades of laughs."
While another commented: "I’m extremely saddened to hear that Mike Hagerty has passed away. I wanted so badly to do a Random Roles with him for the AV Club, but even though he was a Chicago guy, the pitch was a no-go. (1/2)
"Most depressing is that we were supposed to do an interview for my Substack newsletter when SOMEBODY SOMEWHERE premiered, but due to a scheduling issue, it never happened…and now it never will. #RIPMikeHagerty."
A third wrote: "Rest in Peace to Mike Hagerty. If you watched TV/Movies in the 90s, then you know that Mike is one of the all time "That Guys". Always loved when he popped up and his roles in Wayne's World and Seinfeld are legendary."
"Sad to hear of the passing of Second City stalwart and character actor Mike Hagerty, recently seen as the dad on "Somebody Somewhere" on @HBO. Mike had the classic Chicago mustache and accent, and a natural onscreen presence. He always came to play," another commented.
One tweeted simply: "RIP Mike Hagerty one of the funniest actors."
