V552 Cas is a star yet to be systematically studied in the constellation Cassiopeia. The star was first indicated as a RR Lyr star by Götz and Wenzel (1956). The results presented in this paper convincingly demonstrate V552 Cas is a β Lyrae (EB) type eclipsing binary star with a period of 1.32808 days.
