In this study, orbital period analysis of QY Cam eclipsing binary star systems is presented for the first time. Period analysis is performed using the O-C method. Minimum times obtained from Transiting Exoplanet Survey Satellite (TESS) satellite observations and all minimum times given in the literature are used in the O-C analysis. As a result of the parabolic fit to the O-C diagram of the system, which is made using the least squares method, the quadratic term is found to be -1.16(7)x10^(-9) days. This value of the quadratic term indicates that the orbital period of the system decreases regularly with a rate of 0.029(5) s/year. The physical mechanisms that may cause this decrease in the orbital period are discussed.
