Maddex

Meaning & origin

Maddex entered the U.S. baby name charts in 2003 as a modern spelling variant of the surname-derived first name Maddox. Its peak came in 2012, the same year it reached its highest rank, but since 2013 its usage has been declining, reflecting a broader trend away from some of the early-2000s invented-sounding names. In 2025, Maddex ranked #3379, given to approximately 1 in every 50,238 newborn boys. The name has yet to appear in any state's top-name lists, suggesting it remains a niche choice. Maddex is a clear example of the contemporary preference for surnames as first names, softened by the popular 'x' ending. Its longer form Maddox enjoys greater popularity, but Maddex offers a distinctive alternative for parents seeking a less common variant.

Maddex is a modern spelling variant of Maddox, itself derived from the Welsh surname ap Madoc meaning 'son of Madoc.' Madoc is a name of Welsh origin meaning 'fortunate' or 'beneficent.' In the United States, Maddox and its variants gained popularity in the early 2000s, possibly influenced by celebrity usage. Maddex is a less common phonetic respelling that emerged around the same time.
