Meaning & origin

Ostin is a modern English name that first appeared in U.S. birth records in 1992. It is a spelling variant of Austin, which itself comes from the Latin Augustinus, meaning 'majestic.' The name reached its peak popularity in 2023 at rank 4,396, but has been declining since 2022. In its latest recorded year (2025), it was given to approximately 1 in 74,264 boys. Ostin has no strong regional ties; it has not appeared among the top names in any state. Its trajectory suggests it is a niche choice, favored by parents seeking a distinctive spelling of a familiar name.

Ostin is a modern spelling variant of Austin, itself a medieval English vernacular form of the Latin name Augustinus (English Augustine). The root name Augustus, meaning 'venerable' or 'majestic,' was a title of Roman emperors. Ostin emerged in the late 20th century, first recorded in U.S. data in 1992. Its rise may reflect the fashion for alternative spellings of traditional names, though it remains rare.
