Ledecky, the daughter of Mary Gen (Hagan) and David Ledecky, was born in Washington, D.C., and reared in the Bethesda, Maryland, neighbourhood. Dr. Jaromr Ledeck, PhD (1927–2011), her paternal grandpa, was born in Prague, Czechoslovakia (now Czech Republic), to Catholic parents who married at the Kostel svaté Ludmily in Vinohrady. In 1921, his father, a quarter-Jewish procurator, visited America. Jaromr arrived in New York City as a student on September 8, 1947, and subsequently became an economist.

On December 30, 1956, he married Berta Ruth Greenwald , a Jewish lady who had lost family in the Holocaust. Ledecky's mother is from Ireland. Ledecky is a devout Catholic. Jon Ledecky, a businessman and owner of the New York Islanders, is her uncle. Due to the influence of her elder brother, Michael, and her mother, who swam for the University of New Mexico, Ledecky began swimming at the age of six. She graduated from Stone Ridge School of the Sacred Heart in 2015 after attending Little Flower School through eighth grade in Bethesda.

Ledecky twice set the American and US Open records in the 500-yard freestyle and twice established the national high-school mark in the 200-yard freestyle during her high-school swimming career. With the exception of the 100-meter breaststroke, Ledecky ended her high school career as the Stone Ridge school record holder in every swimming event.

She trained at the Nation's Capital Swim Club (previously the Curl Burke Swim Club) under coach Yuri Suguiyama throughout the summer of 2012.
