John Tartaglia is openly gay. Regarding the matter, he has stated "I'm less worried about being a positive role model as a gay person than making sure there's no negative stereotypes of any sort." He considers "nothing more addictive than the sound of an audience laughing" and regarding the possibility of being "pigeonholed" as a children's entertainer, stated "If I get pigeonholed, I get pigeonholed. When I do my dark, one-hour miniseries on Lifetime, you'll know!" In 2004, he helped to raise $525,000 for Broadway Cares/Equity Fights AIDS.
