The invention discloses a bioethanol autothermal reforming hydrogen production system which is characterized in that an electric auxiliary heater, a tail gas catalytic thermal coupling device and an ethanol reforming unit group form a tail gas catalytic thermal coupling ethanol reforming unit module, and one or more tail gas catalytic thermal coupling ethanol reforming unit modules are arranged according to use requirements; vaporized alcohol water is mixed with air treated by the nitrogen separation unit to form raw material gas, and the raw material gas is distributed into one or more tail gas catalytic thermal coupling ethanol reforming unit modules for an ethanol autothermal reforming reaction; the generated high-purity hydrogen is cooled and then supplied to hydrogen use or storage equipment for use; the generated tail gas enters a tail gas catalytic thermal coupling device, the tail gas is subjected to catalytic oxidation to generate CO2 and H2O, and generated heat is supplied to an ethanol reforming un
