The invention discloses an impeller, a fan, an air conditioner outdoor unit and an air conditioner. The impeller comprises a hub, a plurality of main blades and a plurality of auxiliary blades. The multiple main blades are connected with the hub and arranged in the circumferential direction of the hub at intervals. The multiple auxiliary blades are connected with the hub, and at least one auxiliary blade is arranged between every two adjacent main blades. The area of the main blades is larger than that of the auxiliary blades. The maximum vertical distance between the outer edge of the main blade and the central axis of the hub is R1, the maximum vertical distance between the outer edge of the auxiliary blade and the central axis of the hub is R2, and R2 is larger than or equal to 0.85 R1 and smaller than or equal to 1.2 R1. The impeller can effectively improve the air output of a fan without increasing the diameter, is beneficial to improving the heat exchange efficiency of an outdoor unit of an air conditioner, and prevents the fan from additionally increasing the occupied space of the air conditioner.
