The present invention relates to a battery overcharge prevention apparatus for an eco-friendly vehicle which can prevent overcharge even when a battery management system is failed. The battery overcharge prevention apparatus comprises: a detector detecting battery overcharge by monitoring a cell voltage of a battery; and a signal processor controlling a high voltage relay in accordance with an output signal output from the detector to shut off charging of the battery by using regenerative power generated when the vehicle is braked.
