Kailynn

Kailynn is a feminine name that represents a modern blend of the popular prefix 'Kai-' (found in names like Kayla and Kaitlyn) with the trendy suffix '-lynn.' This contemporary combination name emerged during the late 1990s and early 2000s when such creative formations were particularly fashionable. The name has Hawaiian connections through the 'Kai' element, which means 'sea' in Hawaiian, while the 'lynn' suffix has Welsh origins meaning 'lake' or 'waterfall' — creating a name with dual water associations. Kailynn offers parents a melodic, flowing name with a modern feel and natural themes. The double 'n' spelling adds a distinctive touch to this already unique name, which balances trendiness with an appealing sound pattern.

Kailynn is also given to boys.

Pronounced KY-lin.

As of October 2026, Kailynn ranked #9332 for boys in US births in 2023 and #2343 for girls in US births in 2025 SSA, peaked at #899 for girls in 2011.
