Katerina is the Greek and Slavic form of Katherine, a name of uncertain origin that has been linked since early Christian times to the Greek katharos, "pure". It is the everyday form in Greece, the Czech Republic and much of the Balkans and carries the memory of Saint Catherine of Alexandria. In the United States Katerina reached the top 1000 only once, at number 918 in 2000, and has since settled around number 1200 to 1500, ranking 1431 in 2025.
