A vehicle wheel drive device includes: a rotary electric machine that is received on a radially inner side of a vehicle wheel shaped in a cylindrical tubular form and is configured to rotate the vehicle wheel; and a brake device that includes a brake disc and a brake caliper. The brake device is configured to generate a braking force relative to the vehicle wheel. The rotary electric machine includes a rotor and a stator which are opposed to each other in a radial direction. A hollow space is formed on a radially inner side of a magnetic circuit unit that is formed by the rotor and the stator. The brake device is placed in the hollow space in a state where the brake caliper is fixed to an axial end surface of the stator which faces in an axial direction, and the brake disc is rotatable integrally with the rotor.
