Kareen is of Arabic origin, meaning "tender" or "gentle." It is often spelled Kareena, but the variant spelling Kareen is also used. The name gained popularity in English-speaking countries after Indian actress Kareena Kapoor Khan adopted it professionally.
"Kareen's popularity as a baby name peaked in the mid-20th century, with over 24 births each year between 1942 and 1947. However, its usage has significantly declined since then, with fewer than 15 births per year from 1968 onwards. The total number of babies named Kareen from 1921 to 2020 is 1306."
