Pitching is reduced even when strong braking operation is performed during low speed running. A vehicular brake hydraulic pressure control apparatus includes control section (20) that performs pitching reducing control for reducing occurrence of pitching by controlling each control valve unit (V) to switch brake hydraulic pressure between pressure increasing state, pressure decreasing state, and holding state. The control section (20) performs pitching reducing control based on weight distribution ratio between front wheels and rear wheels (FL, RL, RL, RR) during deceleration, and includes distribution ratio calculating section (24) for calculating the weight distribution ratio from deceleration of vehicle, vehicle speed calculating (21) section for calculating vehicle speed, and determining section (23) for determining whether or not to perform pitching reducing control, wherein the determining section (23) determines to perform pitching reducing control if conditions are satisfied, the conditions including at least that the calculated vehicle speed is lower than a predetermined speed and that braking operation is being operated.
