A photometric study of seven new eclipsing binary systems with eccentric orbits, namely, V466 Car, V493 Car, V529 Car, MN TrA, V398 Lac, V402 Lac and V821 Cas, is presented. The photometric data analyzed were taken from the Hipparcos database. The secondary minima in all systems were shifted by different amounts from the phase 0.5 giving clear evidence of their eccentric orbits. The EBOP computer program based upon models by Nelson et al. [Popper, D.M., Etzel, P.E., 1981. AJ 86, 102] was used in the analysis of the photometric data to deduce the orbital geometry in space and the relative sizes and luminosities of the component stars.
