In this study, we conducted the first analysis of spectroscopic and photometric observations of the eclipsing binary star HD 53570. Spectroscopic observations of HD 53570 were made at the Sutherland Station of the South African Astronomical Observatory in 2013 and 2014. The radial velocities of the components were determined using the cross-correlation technique. The spectroscopic mass ratio obtained for the system was 1.13 (+/- 0.07). The All Sky Automated Survey V light curve of HD 53570 was analyzed using the Wilson-Devinney code combined with the Monte Carlo search method. The final model showed that HD 53570 has a detached configuration. The mass and radii of the primary and secondary components of HD 53570 were derived as 1.06 (+/- 0.07) M-circle dot, 1.20 (+/- 0.16) M-circle dot, and 1.42 (+/- 0.14) R-circle dot, 2.07 (+/- 0.16) R-circle dot, respectively. The distance of HD 53570 was computed as 248 (38) pc considering interstellar extinction. The evolutionary status of the component stars was also investigated using Geneva evolutionary models.
