The first high precision CCD photometric light curves of 1SWASP J064501.21+342154.9 were obtained in 2013 February along with several new times of minimum light. The multi-color light curves were analyzed using the Wilson-Devinney code. Photometric solutions reveal that the system is a W-type shallow contact binary with a mass ratio of q = 2.110 ± 0.007 and a degree of contact of f = 15.3% ± 2.1%. A third light contributing about 2% of the total luminosity in the I band was found. It may come from a cool tertiary component. A small spot found on the surface of the binary indicates that the solar-like activities are at a low level at present.
