Dierdra is a female name with origins in Celtic mythology. It is derived from the ancient Irish name Deirdre, which means "sorrowful" or "woman of sorrows." In legend, Deirdre was a beautiful and tragic figure who was pursued by kings and warriors alike. The name Dierdra has a melodic quality to it and is pronounced as DEER-drah in both British English (/ˈdɪərdraː/) and American English (/ˈdɪərdrɑː/). Variations of this name include Deirdre. In the United States, Dierdra has been given to baby girls since at least the mid-20th century. Although its popularity has varied over the years, it continues to be chosen as a unique and meaningful name for newborns.
