Bailie Jaye Key (born March 16, 1999) is a retired American artistic gymnast.

A few weeks later, at the Visa Championships, Key finished fourth in the all-around but got a bronze medal on the balance beam and floor exercise.

Key won gold in the all-around, beam and floor and placed fourth on bars and vault.

In November, Key was selected, along with fellow junior gymnasts Hernandez, Veronica Hults and Emily Gaskins and senior gymnasts Maggie Nichols and Peyton Ernst to represent the United States at the 2013 Mexican Open in Acapulco, Mexico.

Key helped the American juniors take the team title in the International Junior Cup and also won the all-around title ahead of Hernandez, Gaskins and Hults, who finished second, third and fourth, respectively; however, only Key and Hernandez were awarded the gold and silver medals because of a two-per-country rule.

There, she won the all-around, vault and floor medals for the junior division and placed second on uneven bars and balance beam.

On September 14, 2014, Key verbally committed to the Florida Gators women's gymnastics team.

[4] Key turned senior in 2015, consequently becoming age-eligible for a place on the USA Gymnastics team for the 2015 World Championships in Glasgow, Scotland, and for the 2016 Summer Olympics in Rio de Janeiro, Brazil.

She came in second place, behind Simone Biles, in the all-around with a score of 59.500, surpassing both Gabby Douglas and Aly Raisman.

Key was named to the Senior National Team for the first time and received an invitation to the 2015 Worlds Selection Camp in September.

She signed the National Letter of Intent to the University of Alabama and the Crimson Tide gymnastics team on November 10, 2016.
