An apparatus and a method of synchronizing EEG data on the same event and an EEG analysis system using the same are provided to improve intention seizing performance of a user by receiving consistent information to extract characteristics or classify pattern. A conversion unit converts at least two EEG(Electroencephalogram) signals generated on the same event into characteristic information values, and converts the converted characteristic information values into alignment code values. The converted alignment code values are respectively aligned by an alignment unit. A synchronization unit aligns the interesting characteristic value based on the code align information for each code obtained by the alignment unit to synchronize EEG data generated on the same event.
