We present Transiting Exoplanet Survey Satellite (TESS) light curve analysis of KZ Vir. The TESS observations of KZ Vir were published in a total of three Sectors. TESS observations show some features that could not be observed with ground-based telescopes before. We refined the light elements of the system by using the times of minima found in the literature and the times observed with TESS. The TESS light curve was analyzed with the Wilson-Devinney code including geometric and physical parameters of the components obtained using published radial velocity data. We confirmed for the first time that the system is essentially a detached type eclipsing binary and obtained masses and radii of the primary and the secondary components: M₁=1.596±0.022 M_☉, M₂=1.319±0.019 M_☉ and R₁=2.271±0.011 R_☉, R₂=1.603±0.008 R_☉, respectively. We find that the components of KZ Vir are located above or on the TAMS.
