Regina is a female given name of Latin origin, meaning "queen" or "royal". It was popularized during the Middle Ages as the name of several European saints and queens. The name's popularity has fluctuated over time, with peaks in usage in the early 20th century and again in the late 1980s to early 1990s. Regina is often associated with the feminine qualities of grace, elegance, and strength. It shares its root with the male name Reginald, as well as the name Reggie for both boys and girls. Notable figures named Regina include Regina King, an American actress known for her roles in "The Boondocks" and "Watchmen", and Regina Hartley, a Canadian ice hockey player who won gold at the 2006 Winter Olympics. Variations of the name include Reina, Reygana, and Reginae.
Reginia had its highest popularity from the late 1940s to the mid-1970s with a peak of 49 births in 1962 and an average of about 40 births per year during this period. However, it started declining thereafter, dropping below 10 births per year from 1985 onwards, indicating that the name has largely fallen out of favor since then.
