Provided is a wheel loader capable of reducing erroneous determination of rear wheel lifting. The wheel loader 1 includes a controller 5 for determining a rear wheel lifting state where rear wheels 11B are lifted upwardly. The controller 5 is configured to, when a temporal change rate α of a bucket operation angle becomes a temporal change rate of a bucket operation angle necessary for a tilt operation of a bucket 23 during an excavation operation and a temporal change rate β of a vehicle body inclination angle estimated by the controller 5 becomes a temporal change rate of an obliquely upward inclination state of a rear vehicle body with respect to a front vehicle body, turn on a correlation flag indicating a correlation between an operation state of the bucket 23 and an inclination state of a vehicle body to determine a rear wheel lifting.
