Justin is the English form of the Roman name Justinus, from the Latin justus, meaning "just" or "fair." The English word justice has the same root. It is pronounced JUSS-tin, with the stress on the first syllable.
The name was borne by Saint Justin Martyr, a second-century philosopher who wrote in defense of Christianity, and by the sixth-century Byzantine emperors Justin I and Justin II. Modern namesakes include singer Justin Timberlake and former Canadian prime minister Justin Trudeau.
In the United States, Justin climbed from 293rd in 1967 to 13th in 1980 and peaked at No. 7 in 1988, when 35,055 babies received the name. It has become much less common since then and ranked 233rd in 2025, with 1,512 babies.
