In 2025, Mathius ranked 5,861 with a frequency of 1 in 113,872 births, making it an uncommon choice that appeals to parents seeking a distinctive twist on a traditional name.

Mathius is a modern respelling or variant of Matthias, which itself derives from the Greek Maththaios, a form of the Hebrew name Mattityahu, meaning 'gift of Yahweh.' The spelling with 'u' instead of 'a' or 'ia' is a contemporary invention, likely influenced by other names ending in -ius. It has seen occasional use in the United States since the early 2000s.
