I conducted photometry of the cataclysmic variable ASASSN-V J090756.65+715859.5 and detected eclipses that were not previously known. I observed 12 eclipses. Photometric data were obtained in two compact groups of nights separated by one year. Due to the large coverage of observations and due to the fact that all eclipses had a small scatter of points, I very precisely determined the orbital period, d. The eclipse profile was asymmetric similar to eclipse profiles seen in other cataclysmic variables. The eclipse depth varied in the range 0.83(1)–1.56(4) mag and strongly correlated with the out-of-eclipse magnitude, which showed only small variations resembling stunted outbursts of nova-like variables and was between 15.22(2) and 16.12(8) mag. Using the eclipse width at half the depth (0.0563(7) phases), I estimated the minimum inclination of the orbit (
) and the maximum absolute magnitude of the disc, 5.5–5.6 mag. This suggests that ASASSN-V J090756.65+715859.5 is a nova-like variable. I derived the long-term eclipse ephemeris, the actual validity of which is 400 years. This ephemeris is very good for studying changes in the orbital period. In addition, this ephemeris is useful for computing the orbital phases.
