Meaning & origin

Case is a modern given name that emerged as a short form or spelling variant of Casey, itself derived from the Irish surname Ó Cathasaigh. In 2025, it ranked 733rd for boys, with a 1-in-4,758 birth rate, reflecting its steady but moderate usage. Its peak popularity occurred in 2014, after which its trajectory has been slightly falling since 2013. Case has been recorded since 1959, indicating its relatively recent adoption as a first name. The name is most common in Oklahoma, Arkansas, and Utah, regions where traditional and surname-style names often hold appeal. While Case lacks deep historical roots as a given name, its clear pronunciation and strong, one-syllable sound make it a modern choice that fits alongside similar streamlined names.

Case is a modern variant of Casey, which comes from the Irish Gaelic surname Ó Cathasaigh, meaning 'descendant of Cathasach', a personal name derived from 'cathas' meaning 'vigilant' or 'watchful'. It emerged as a given name in the late 20th century, particularly in the United States, where it gained popularity as a short, strong-sounding alternative to longer Irish surnames.
