Disclosed is a travel control apparatus for a four-wheel drive vehicle in which the states of engagements between a drive output part for secondary drive wheels and left and right secondary drive wheel axles are each changed to a torque transmission state or a torque transmission interruption state. The ratio of rotational speed of the drive output part to the average of rotational speeds of primary drive wheels is greater than 1. When the engagement states corresponding to the secondary drive wheels on the outer and inner sides of a turning locus have been set to the torque transmission state and the torque transmission interruption state, respectively, the engagement state having been set to the torque transmission state is changed to the torque transmission interruption state upon determination that an accelerator pedal is not operated and the magnitude of lateral acceleration is equal to or greater than a predetermined threshold.
