Meaning & origin

Kathryn is a feminine name of English origin, a familiar variant of the classic Katherine. In 2025, it held the rank of 729 in the United States, given to about 1 in 4,219 baby girls. The name's peak popularity came much earlier, in 1951, when it was a top favorite. Since then, its usage has steadily declined, with a notable falling trajectory beginning around 1985. Despite this, Kathryn remains a recognized choice, particularly in states like Alabama, South Carolina, and Pennsylvania. Its enduring appeal lies in its blend of traditional roots and a slightly modernized spelling, making it a subtle alternative to the more common Catherine or Katherine.

Kathryn is a spelling variant of Katherine, an English name derived from the Greek Aikaterine. The name's exact derivation is uncertain, though it has been associated with the Greek 'katharos' meaning 'pure' since the early Christian era. It was introduced to England by returning Crusaders in the 12th century and became highly popular due to Saint Catherine of Alexandria. The spelling with a 'K' and 'y' gained traction in English-speaking countries in the 20th century, offering a distinctive twist on a classic name.
