U, B, V photometry of the eclipsing binary DX Aqr is presented. The period of the system comes out to be nearly half the period given by Strohmeier (1966) and a value of 0.472502 d is determined. The color of the system is discussed. It is shown that the primary eclipse is a total occultation, that the orbit seems to be eccentric, and that the system belongs to Algol type. DX Aqr may be a very complicated system. The present results are considerably different from those of earlier investigations by Strohmeier et al. (1965), Strohmeier (1966), Cowley et al. (1969), and Olsen (1976).
