Meaning and history
Jay began as an English short form of names starting with the J sound, including James and Jason. It was also used in early America in honour of statesman and first U.S. chief justice John Jay, whose surname came from the name of the jay bird. The compact form later became an independent given name; notable bearers include comedian Jay Leno and musician Jay-Z, born Shawn Carter.
Jay rose from #396 to #392 for boys between 2024 and 2025. Its highest annual birth count came in 1960, with 5,385 births.
