Abstract
New times of minima of the Algol-type eclipsing binary UZ Sge, obtained at the Athens University Observatory, have been used together with all reliable timings found in the literature in order to study the period variation and search for the presence of a third body in the system. Its O-C diagram is presented and apparent period changes are discussed with respect to possible Light-Time Effect (LITE) in the system. A least square method has been used to compute new light elements (updated ephemeris of binary) as well as the mass function, its minimum mass and the period of a possible third body.
