Meaning & origin

Fitz is a rare and distinctive given name, derived from the Norman French prefix meaning 'son of.' It first appeared in U.S. records in 1914, but has seen more consistent use only in the 21st century. Its peak popularity occurred in 2020, when it reached its highest rank, though it has been gradually declining since then. With a 2025 rank of 3,450 and a frequency of 1 in 51,760 births, Fitz remains uncommon. The name is almost exclusively given to boys, reflecting its historical association with masculine surnames like Fitzgerald and Fitzpatrick. Unlike many surname-based names, Fitz has no strong regional concentration; its top states are broadly distributed. As a modern coinage, it lacks the deep etymology of ancient names but offers a crisp, surname style that appeals to parents seeking a short, punchy name with a noble sound.

Fitz originates from the Norman French prefix 'fitz' (from Latin 'filius'), meaning 'son of.' It was commonly used in medieval England to form patronymic surnames, such as Fitzgerald or Fitzroy. As a given name, it emerged as a modern coinage, likely derived from such surnames.
