Meaning & origin

Cylas is a modern American name that first entered the U.S. baby name charts in 1996. Its spelling with a 'C' distinguishes it from the more traditional Silas, contributing to its steady rise in use since 1998. The name reached its peak popularity in 2015, when it ranked highest among parents seeking a contemporary-sounding name with biblical roots. In 2025, Cylas ranked 2,183rd overall, with approximately 1 in every 26,278 newborn boys receiving the name. Its strongest geographic presence is in Ohio, where it appears most frequently. As a recent coinage, Cylas lacks a deep etymological history, but its resemblance to established names like Silas and Cyrus gives it a familiar yet fresh appeal.

Cylas first appeared in U.S. birth records in 1996. It is almost certainly a modern invented name, possibly a respelling of the biblical name Silas (from Latin Silvanus, meaning 'of the forest') or an elaboration of Cyrus (from Persian, meaning 'sun'). Its spelling with a 'C' gives it a distinctive, contemporary feel.
