The Kepler mission observed over 2200 eclipsing binary stars in its 105-square degree field of view. Their importance in modern astrophysics cannot be overstated -- it ranges from deriving the fundamental stellar parameters across the Hertzsprung-Russell Diagram and calibrating the mass-radius-temperature relationships, to determining the distances in the Galaxy and beyond. Kepler observations provide a unique sample with a nearly continuous coverage and sub-millimag precision, allowing us to model binary star light curves to unprecedented accuracy. In the context of planet hunting, the period and amplitude statistics derived from this sample are used to estimate the occurence rate of false positives: stellar sources that mimic planet transits due to third light contamination. I will present the results of the studies performed by the Kepler Eclipsing Binary Working Group: 1) determining the physical parameters of binary star components, 2) studying the eclipse timing variations that attest to the presence of third bodies or arise due to component interaction, 3) performing statistical analysis of the whole sample, 4) estimating the occurence rate of background eclipsing binaries, and 5) searching for tertiary events due to other eclipsing objects. This work is supported by the NASA/SETI grant 08-SC-1041 and NSF RUI #AST-05-07542.
