Astrid has been a Scandinavian royal name since the tenth century, and many people associated it with the Swedish author of the Pippi Longstocking stories, Astrid Lindgren. Astrid is derived from the name Ástríðr, which is made up of the Old Norse elements that mean "god" and "beautiful." 
Related names include Asta, a diminutive used throughout Scandinavia, and Astride, the French form. Despite their similarities, Astrid is unrelated to Astra, a Latin name meaning "of the stars."
