Name origin (IAU): Cè (Whip, 策) is an ancient Chinese star name representing the horsewhip, located beside the asterism Wangliang (王良) and closely associated with both Wangliang (王良) and Tiansi (天駟). It belongs to the Gān school. "Xing" means star. The ancients sometimes also call it Cexing (whip star) or Tiance (celestial whip). In modern and postmodern literature in English, the name is occasionally used for γ Cas but this is a late shift, only attested from the 18th century onwards when the Chinese uranography was reworked under Jesuit influence. WGSN corrects the adoption to the Indigenous version.

Its IAU name «Cexing» comes from Chinese (IAU Working Group on Star Names).
