Meaning & origin

Sevastian is a distinctive variant of the classic name Sebastian. First recorded in the United States in 1988, it peaked in popularity in 2008 but has since remained stable in usage. In 2025, it was ranked 8,910 with a frequency of 1 in 213,510 births. It has not yet ranked in the Social Security Administration's top 1,000 names, making it a rare choice. Its spelling sets it apart while retaining the familiar sound of Sebastian, offering a unique option for parents seeking a name with historical roots.

Sevastian is a variant of Sebastian, which derives from the Latin name Sebastianus, meaning 'from Sebastia'. Sebastia was a city in Asia Minor (modern Sivas, Turkey), named after the Greek word 'sebastos' (venerable). The name Sebastian was popularized by early Christian martyr Saint Sebastian. Sevastian is a less common spelling that emerged in the late 20th century, particularly in the United States.
