Provided are a motor rotor capable of effectively separating gas and oil to prevent undesired oil discharge and oil deficiency, and a compressor having the motor rotor. The motor rotor (1) has a rotor core (2), at least one gas passage (7), and an oil passage (8). The rotor core (2) is formed by stacking steel plates (3). The gas passage (7) penetrates through the rotor core (2) in its axial direction and allows gas to flow in it from a first axial end (9), which is one axial end of the rotor core (2), to a second axial end (10) on the side opposite the first axial end (9).The oil passage (8) is located inside the rotor core (2), at a position closer to the radially outer side of the rotor core (2) than the gas passage (7). The oil passage (8) causes oil to flow in it in the direction from the second axial end (10) to the first axial end (9), that is, in the direction opposite the direction of the flow of the gas in the gas passage (7).
