Meaning & origin
Maddux is a modern surname-turned-first-name that entered the U.S. baby name charts in 1996, a remarkably recent debut for a name now familiar to many. Its rise was swift: by 2018 it reached its peak rank of 1529, but has since been falling in popularity, with 2025 data showing a continued decline from 2017 onward. The name is most prevalent in Iowa, Tennessee, and Utah, suggesting a concentration in the Midwest and Mountain South. Its one-in-15,116 frequency in 2025 places it firmly in the uncommon but not obscure category. The Welsh-derived meaning 'fortunate' offers a positive connotation, while the baseball association with Greg Maddux gives it a distinctively American, athletic flavor. Though not as common as the Maddox spelling, Maddux maintains a crisp, two-syllable sound that fits well with contemporary naming trends favoring surnames and strong, simple names.
Maddux is a patronymic surname derived from the Welsh personal name Madoc, which is composed of the elements 'mad' (fortunate, good) and the diminutive suffix '-og'. The name Madoc is historically associated with a legendary Welsh prince said to have discovered America in the 12th century, but this tale is unsubstantiated. As a given name, Maddux dates only to the late 20th century, likely influenced by the fame of baseball pitcher Greg Maddux (born 1966), whose surname became a first name.
