A control device for a lockup clutch is provided in which when control region determination device determines that a vehicle speed and an opening degree of an accelerator pedal are in the tight region of the lockup clutch, even if the water temperature of cooling water of the or the oil temperature of hydraulic oil of the transmission is less than a predetermined temperature, engagement permission device permits engagement of the lockup clutch. It is therefore possible to improve the fuel economy of the vehicle by increasing the frequency of engagement of the lockup clutch without affecting the function of the lockup clutch. The control device even functions when the lockup clutch is engaged at low temperatures, when the engagement responsiveness is low, because the oil temperature of the hydraulic oil is low and the viscosity is high.
