A vehicle rear wheel lift tendency judgment device: includes a first deceleration obtaining device for obtaining a first deceleration along a first straight line, being a component in a first direction of an acceleration on a center of gravity, and a second deceleration obtaining device for obtaining a second deceleration along a second straight line, being a component in a second direction of the acceleration; judges that a rear wheel tends to be lifted, when the first deceleration is greater in the first direction than a first threshold, or when the second deceleration is greater in the second direction than a second threshold; and performs at least one of setting for shifting the first threshold in a direction opposite to the first direction and setting for shifting the second threshold in a direction opposite to the second direction, when a second-deceleration change rate being a change amount in the second deceleration per unit time becomes greater in the second direction than a change-rate threshold, enabling a quick judgment of a rear wheel lift tendency.
