In a method and apparatus for diagnosing voltage abnormality of a battery cell in an eco-friendly vehicle, the method for diagnosing voltage abnormality of a battery cell in an eco-friendly vehicle includes the steps of determining whether a voltage deviation of at least one cell of a plurality of cells forming a battery occurs at or above a first threshold voltage a threshold number of times or more than the threshold number during a one-cycle discharge period of the battery, and concluding that voltage deviation abnormality has occurred in the at least one cell if the voltage deviation of the at least one cell has occurred at or above the first threshold voltage the threshold number of times or more than the threshold number.
