The invention discloses an electroencephalogram signal quality evaluation method and device, a terminal and a medium, and the method comprises the steps: determining an energy ratio of a power frequency signal for a multi-channel electroencephalogram signal based on the to-be-processed multi-channel electroencephalogram signal; after the multi-lead electroencephalogram signals are preprocessed, multiple index parameters for the multi-lead electroencephalogram signals are determined; determining a quality evaluation score of the multi-lead electroencephalogram signal according to the energy ratio and the plurality of index parameters; according to the method, the signal quality is quantized into the quality evaluation score by combining a mode of quantizing the signal quality by multiple indexes, so that the effects of comprehensively considering the influence degree of different indexes on the signal quality and improving the signal quality evaluation accuracy are achieved; the problem of poor evaluation prec
