Griffin was born July 6, 1925, in San Mateo, California, to Mervyn Edward Griffin, Sr., a stockbroker, and Rita Elizabeth Griffin (nee Robinson), a homemaker. The family was Irish American. Raised as a Roman Catholic, Griffin started singing in his church choir as a boy, and by his teens was earning extra money as a church organist. His abilities as a pianist played a part in his early entry into show business.

Griffin kept many details of his personal and business life private. In 1991, he was sued by Deney Terrio, the host of Dance Fever, another show Griffin created, alleging sexual harassment. The same year, Brent Plott, a longtime employee who worked as a bodyguard, horse trainer and driver, filed a $200 million palimony lawsuit. Griffin characterized both lawsuits as extortion. Griffin's Los Angeles Times obituary repeated a 1991 statement he had made regarding Plott's lawsuit: "This is a shameless attempt to extort money from me. This former bodyguard and horse trainer was paid $250 a week, lived in one of two apartments underneath my former house as part of his security function, and left my payroll six or seven years ago. His charges are ridiculous and untrue." Ultimately, both suits were dismissed. He consistently evaded answering questions about his sexuality with a characteristic quip. In an interview with The New York Times published on May 26, 2005, Griffin said: "I tell everybody that I'm a quarter-sexual. I will do anything with anybody for a quarter." Until his death, Griffin remained friends with his ex-wife Julann Griffin, whom he credited with creating the premise of Jeopardy! On being wealthy, he said that "if people know you're rich, they don't talk with you when you walk down the street." He kept his wealth an open secret, amassing media outlets, hotels and casinos with a net worth widely estimated at more than a billion dollars. Griffin stated he did not really know his worth because it "would keep me from sleeping at night". Former First Lady Nancy Reagan and he exchanged birthday greetings each July 6 for their shared birthday.
