The invention provides an insulator hydrophobicity evaluation method and system based on laser-induced photoluminescence, and the method comprises the steps: enabling a preset number of insulator samples manufactured according to a preset size to be soaked in distilled water according to an incremental soaking time sequence, and obtaining a to-be-analyzed sample; the method comprises the following steps: respectively measuring a contact angle of each to-be-analyzed sample to obtain a corresponding hydrophobic angle, measuring the fluorescence intensity of each to-be-analyzed sample through a pre-established photoluminescence measuring device, and fitting according to the hydrophobic angle and the fluorescence intensity of each to-be-analyzed sample to obtain a hydrophobicity prediction model; and after the actually measured fluorescence intensity of the insulator to be detected is obtained through the photoluminescence measurement device, the corresponding hydrophobic angle prediction value is obtained accord
