Stacy, sometimes spelled Stacey, Staci, Staecy, or Stacie, is a common unisex first name for women, and occasionally men. The most common male spelling is "Stacy". 　　The meaning of the name is disputed. Baby-naming guides cite two alternative English derivations of Greek origins; Anastasia meaning "resurrection" for girls, and Eustace (Eustachios) meaning "bountiful grain" for boys. 　　Other related names include Eustacia, Stasia, and Stasha.
