Kaylin is an attractive, feminine given name of American origin. It was introduced to popularity by author Dan Gutman's "My Weird School" series, featuring a character named Kayla Kinney, often spelled as Kaylin in subsequent books and adaptations. While it shares similarities with the established names Kaylee and Kailyn, Kaylin stands out as a unique variant with its own charm. The name is composed of two parts: "Kay," which is derived from the name Catherine, meaning pure or innocent, and "lin" which may be inspired by the English word 'line'. It is often spelled Kaylyn as well, but Kaylin is more prevalent in popular culture. As a unisex name, it can also be considered for boys, though it's more commonly used for girls. Kaylin has gained recognition due to its use in media and literature, making it a contemporary choice for parents seeking distinctive yet approachable names for their children.
The name Kaylin saw a significant increase in popularity from the late 1980s to the early 2000s, with peaks in 1994 (26 births) and 1998 (28 births). However, it has since declined, with only 5 births recorded in 2016. As of 2023, there have been a total of 612 babies named Kaylin.
