About Keilyn
Keilyn is a contemporary feminine name that has gained modest popularity since the early 2000s. It appears to be a creative blend of the popular prefix "Kei-" (as in Keisha or Keith) with the trendy suffix "-lyn" that characterizes many modern feminine names like Brooklyn and Madelyn. The name may also be influenced by traditional Irish names like Caoilfhionn or Kaylyn. Keilyn has a melodic, flowing quality with its two syllables and soft ending. While not among the top-ranked names, it appeals to parents seeking something modern and distinctive without being completely unfamiliar. The name works well cross-culturally and has a contemporary feel without seeming invented or difficult to pronounce.
Keilyn is also given to boys.
Pronounced KAY-lin.
As of October 2026, Keilyn ranked #4606 in US births in 2025 SSA, peaked at #2813 in 2009.
