The purpose of the present invention is to provide a vehicle lock-up clutch control device that suppresses engine racing when a lock-up clutch is engaged at the time a vehicle starts moving. A torque converter (4) having a lock-up clutch (3) is disposed between an engine (1) and a continuously variable transmission (6). A vehicle is provided with an initial-motion lock-up control means that, if a line pressure, which is the source pressure of the actual lock-up oil pressure, is rising when the lock-up clutch (3) is engaged at the time the vehicle starts moving, delays the rise in lock-up command pressure. The initial-motion lock-up control means executes a torque reduction in the engine (1) at least during the delay in lock-up command pressure.
