An apparatus and method for estimating a vehicle pitch relative to a road. The apparatus includes a wheel speed sensor part which obtains wheel speed data, an inertial measurement unit (IMU) sensor part which obtains IMU data, a preprocessing part which extracts a stop section and a moving section on the basis of the wheel speed data and the IMU data, and a slope estimation part which estimates a vehicle pitch in the stop section and a road slope in the moving section and estimates a vehicle pitch relative to a road on the basis of the vehicle pitch and the road slope.
