Cynthia is a feminine given name originally used as an epithet for the Greek goddess Artemis, referencing her legendary birthplace on Mount Cynthus on the island of Delos, and was also applied to the moon goddesses Selene and Roman Diana. Although often thought to be purely Greek, the "inth" element suggests a Pre-Greek origin, and the name has been used in the Anglosphere since the 17th century. It enjoyed significant popularity in the 20th century, ranking among the top 100 names for girls in the US from 1945 to 1993, peaking in the top 10 between 1956 and 1963, though it has since declined to 806th place in 2021, with similar popularity in Canada, the UK, France, and Spain. Common nicknames include Cindy, Cyndi, Cyndy, and occasionally Thea or Tia. The name is prominent in pop culture, appearing in works like the Pokémon video games (champion Cynthia), DC and Marvel comics, and TV shows such as The Brady Bunch and The Adventures of Jimmy Neutron.
