Aly Raisman (born Alexandra Rose Raisman, 1994) — American gymnast; team captain of both the Fierce Five (London 2012) and the Final Five (Rio 2016) US gymnastics teams; three Olympic gold medals (team gold 2012 and 2016, floor exercise gold 2012). Six Olympic medals total; first American female gymnast to win gold on floor exercise. *Her 2018 victim-impact statement before sentencing of Larry Nassar — naming him directly and addressing him in court — was a national moment in survivor advocacy; published memoir Fierce: How Competing for Myself Changed Everything (2017). Brand partnership and Sports Illustrated model. Aly is also a diminutive of Alyssa, Alison, or Alyson — a generally feminine first name in the United States since 2010. Aly & AJ* — Michalka sisters, pop duo.
Subject of countless 2010s gymnastics histories.
Aly does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Aly reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
