Maddison is an English surname meaning son of Maud or Matthew, now widely used as a modern given name.
Maddison is a spelling variant of Madison, a surname that originally meant "son of Maud" or "son of Matthew," depending on the family line and region in which it developed. In practice, the most commonly cited explanation is that it emerged as a patronymic or metronymic surname in medieval England, shaped by the fluid spelling habits of the time. As with many English surnames, what began as a marker of descent eventually became a first name centuries later.
The shift from surname to given name is central to Maddison’s story. Madison entered wider first-name use in the United States in the 20th century, but its explosive popularity is often linked to the 1984 film Splash, in which the character Madison famously adopts the name from Madison Avenue. That pop-cultural moment transformed an old surname into a sleek modern first name.
The spelling Maddison, with the doubled "d," arrived as families sought a softer or more visually elaborate variant, distinguishing it from the increasingly common standard form. Over time, Maddison has become strongly associated with contemporary femininity, even though its surname roots are not gendered in that way. It fits alongside names like Addison and Allison, where surname history merges with fashionable sound patterns.
The doubled consonant gives it a slightly more ornamental, modern feel, and nickname options like Maddie make it especially approachable. Today Maddison is often perceived as lively, polished, and familiar, a name born from medieval lineage but reshaped by modern taste, media influence, and the rise of surname-style naming.
