A vehicle turning behavior control apparatus comprises a controlling section which limits a turning behavior of a vehicle caused by a steering operation, to a limit behavior corresponding to an actual steering speed, by a vehicle speed decrease. The controlling section is configured to determine a modified steering speed in accordance with the actual steering speed, and to determine the limit behavior in accordance with the modified steering speed. The controlling section is further configured to make the modified steering speed higher than the actual steering speed when the actual steering speed decreases during a turning steering for increasing a steering amount. For example, the actual steering speed is used directly as the modified steering speed while the actual steering speed during the turning steering is increasing. While the actual steering speed during the turning steering is decreasing, the modified steering speed higher than the actual steering speed is used.
