Austyn is a feminine respelling of Austin, the medieval English form of Augustine, which comes from the Latin augustus and means "great" or "venerable". The y spelling turns a classic boys' name and Texas city into a modern girls' choice in the style of Peyton and Jordyn. In the United States Austyn ranked number 5000 for girls in 2000, entered the top 1000 in 2018, peaked at number 920 in 2021 and stands at number 1389 in 2025.
