Keyler is a modern spelling variant of Kyler, itself an American creation that blends Kyle, from the Gaelic word for "narrow strait", with Tyler. The spelling with -ey is especially popular among Spanish-speaking families, where the goalkeeper Keylor Navas is a familiar bearer of the near-identical Keylor. Keyler rose from around number 4800 in 2015 to number 1759 among boys' names in 2025, its best rank yet.
