The invention discloses a bionic jet flow testing device for hydrofoil surface cavitation resistance. The bionic jet flow testing device comprises a waterway circulation system, a jet flow supply system and a jet flow control system, wherein the waterway circulation system provides waterway circulation required by overflow for a hydrofoil, the jet flow supply system is used for providing circulation of a jet flow, and the jet flow control system is used for adjusting the size and direction of the jet flow. The bionic jet flow testing device can significantly reduce the cavitation influence onthe surface of the hydrofoil and improve the flowing condition through arranging a jet flow structure inside the hydrofoil through adopting a bionic structure design, can reduce the friction between afluid and a solid contact surface, reduce the friction resistance between a main flow field and a contact wall surface in the flowing process, reduce the energy loss, improve the conveying efficiency, saves energy, further ca
