Disclosed are a device and a method for optimal electrode selection for brain-computer interface (BCI) using a correlation and a Fisher ratio of filter bank common spatial pattern (CSP) features. The electrode selection device comprises: a first electrode selection unit for calculating correlation between a plurality of EEG signals measured from each of a plurality of electrodes, each of which is attached to a subject′s head, and for selecting first electrodes among the plurality of electrodes based on a Fisher ratio for correlation; and a second electrode selecting unit for grouping the first electrodes into a plurality of sub-regions, extracting features for each sub-region, and selecting second electrodes from the first electrodes using the extracted features.
