Kacelyn

Kacelyn is a modern invented name, given to around 15 girls every year. It combines the unisex Kacey with the popular suffix, -lyn, giving it the possible meanings "brave in battle, but soft and tender too"; "vigilant one by the lake", or "watchful and pretty", depending on which etymological roots you decide you want to blend.

While Kacey (and its spelling variants, Kasey, Kayce, and Casey) are less popular for girls than they once were, Kacelyn follows the pattern of Raelynn, Katelyn, and Gracelyn, which might mean it sees more use.

Kacelynn V is musician who bears the name.

Pronounced KAY-se-lin.

As of October 2026, Kacelyn ranked #3804 for girls in US births in 2025 SSA.
