Meaning & origin
Sebastain is an uncommon variant spelling of the classic name Sebastian. First recorded in U.S. data in 1918, it reached its peak rank of 8,243 in 2002 and has been falling in popularity since 2001, with a trajectory indicating continued decline. In 2025, it was given to roughly 1 in every 189,786 boys, making it a rare choice. While Sebastian itself has been a long-standing favorite, the Sebastain spelling remains an offbeat alternative for parents seeking a distinctive twist on a familiar name.
Sebastain is a variant spelling of Sebastian, derived from the Latin Sebastianus, meaning 'from Sebaste'. Sebaste was a city in Asia Minor named after the Greek word σεβαστός (sebastos), meaning 'venerable' or 'august'. The name Sebastian was popularized by the early Christian martyr Saint Sebastian, who was executed in the 3rd century. Sebastian has been in use in England since the Middle Ages and saw a revival in the 20th century. The spelling Sebastain appears as a modern respelling.
