The disclosure relates to a steering system for a mobile work machine, in particular for a mobile crane, which comprises at least one mechanically steerable front axle, at least one passively-steered rear axle, as well as at least one rear axle that is steerable by means of at least one steering cylinder. The front and rear axles are arranged one behind the other along a longitudinal axis of the steering system and comprise wheels, the axes of rotation of which, virtually extended, in the case of cornering, on the side of the curve center, intersect a common steering pole plane positioned perpendicularly on the longitudinal axis. According to the disclosure, at least one passively-steered rear axle is arranged between a front axle and the steering pole plane. The disclosure furthermore relates to a mobile work machine comprising such a steering system.
