Ken Jennings, born May 23, 1974, is a Gemini game show host and author who has hosted Jeopardy! since 2021. He won 74 consecutive Jeopardy! games in 2004, the longest streak in the show's history, earning $2,522,700 during his original run and over $4.5 million across all game show appearances. The former software engineer parlayed his quick-recall abilities and communication skills into a career as the face of America's most iconic quiz show.

Jennings grew up in South Korea and Singapore for 11 years, where his international lawyer father worked, and he watched Jeopardy! on American Forces Network. He graduated from Seoul Foreign School, earned a double major in English and computer science from Brigham Young University in 2000, and worked as a software engineer for CHG Healthcare Services in Utah. He took the Jeopardy! contestant exam in 2003 and prepared for three weeks using a couch as a podium and his young child's toy as a buzzer while his wife used flashcards.

Jennings is married and has children, and he balanced family life with his software engineering career before becoming a game show celebrity. He is a member of the Church of Jesus Christ of Latter-day Saints and spent two years as a volunteer missionary in Madrid, Spain, during his college years. His wife helped him prepare for Jeopardy! by using flashcards and keeping score during practice sessions at home.
