The present invention relates to an apparatus and a method for estimating a vehicle velocity. The apparatus includes: an inertial sensor which measures six degrees of freedom of a vehicle; a vehicle inner sensor which measures vehicle information; a first longitudinal velocity and lateral velocity estimation unit which estimates a kinematics model-based longitudinal velocity and a lateral velocity by using the six degrees of freedom measured by the inertial sensor; a second longitudinal velocity and lateral velocity estimation unit which estimates a physical model-based longitudinal velocity and a wheel speed-based lateral velocity by using the vehicle information; and a vehicle velocity estimation unit which estimates a vehicle velocity by using the estimated figures of the longitudinal velocities and the lateral velocities output from the first longitudinal velocity and lateral velocity estimation unit and the second longitudinal velocity and lateral velocity estimation unit.
