Raisman was born on May 25, 1994, in Needham, Massachusetts, to Lynn (née Faber), a former high school gymnast, and Rick Raisman. She has three younger siblings: Brett, Chloe, and Madison. Raisman began gymnastics when she was two years old. She attributes her initial love for the sport to the "Magnificent Seven", the gold-medal-winning U.S. women's team at the 1996 Summer Olympics, whose performances she watched on VHS. She trained at Exxcel Gymnastics and Climbing through Level 8, when she moved to Brestyan's American Gymnastics Club under coaches Mihai and Silvia Brestyan. There, she trained alongside Alicia Sacramone, of whom she said, "She's kind of like my older sister. I can ask her about anything because I know that she's been through it all." Raisman graduated from Needham High School in 2012, after completing her senior year via online classes while training for the Olympics.
