A system and method for preventing instability of a vehicle due to regenerative braking of a rear wheel are provided, which previously reduce a regenerative braking amount, thus securing vehicle stability and updating a regenerative brake map according to a braking situation, may include a first controller configured of distributing braking torque of front and rear wheels for a deceleration level according to a basic regenerative braking distribution ratio on a regenerative brake map on the basis of a driver demand braking amount, and configured of previously reducing a rear-wheel regenerative braking torque of the rear wheel to a first reference value or less than the first reference value in an adjustment section between first and second deceleration; and a second controller connected to the first controller and configured of further reducing the rear-wheel regenerative braking torque to transmit it to the first controller, if a wheel slip value is greater than a reference slip value according to vehicle driving information during braking of the vehicle.
