The CoRoT satellite is planned for launch in the Fall of 2006. Its scientific goals are two core programs (asteroseismology and exo-planet search) and parallel science (Additional Programs). CoRoT will have a strong impact on our understanding of close binaries, thanks to its high precision photometry (70 ppm) and continuous monitoring (150d) of the same field. Selected binary systems can be chosen, within the Additional Programs frame, as targets of long and continuous pointed observations. Moreover, the database of variable stars from the exo-planet search program will provide light-curves of prime quality for many thousand, mostly unknown, systems. This will allow for studies of fine effects on the light curves, of stellar activity and, in combination with ground-based observations, very accurate determination of fundamental stellar properties. Many new discoveries of interesting systems are expected, including those of low mass binaries. Besides, the mission will promote a quick development of the young field of asteroseismology in close binaries. A different binary-related topic, crucial to the success of the mission, is that of handling background binaries, which, according to simulations, will be main source of false alarms in exo-planet detection. The many aspects of binary-related research in CoRoT are coordinated by the "CoRoT Binary Thematic Team", which gathers the expertise and coordinates the work of scientists from the contributing countries.
