♀ Madison (girl) Madison [madi-son] as a girls' name (also used less regularly as boys' name Madison) is pronounced MAD-a-son. It is of Old English origin, and the meaning of Madison is son of the mighty warrior. Also possibly variant of Madeline (Hebrew) woman from Magdala, or surname derived from Matthew (Hebrew) gift of the Lord or Matilda (Old German) mighty in battle. The mermaid heroine Madison in the hit film Splash probably influenced the use of the surname and boy's name as a girl's name.
