Katrina is a German and Scandinavian form of Katherine, a name of Greek origin that has long been interpreted as "pure", from katharos. It was a staple of American girls' names in the 1970s and 1980s, but Hurricane Katrina in 2005 ended its run almost overnight. Katrina ranked 236 in the United States in 2000, left the top 1000 in the 2010s and stands at number 2226 in 2025 with 83 births.
