PROBLEM TO BE SOLVED: To provide a rear wheel toe angle control device for a vehicle, capable of improving the stability of the vehicle by appropriately controlling a rear wheel toe angle regardless of a road surface condition, tire characteristics or weight of the vehicle. SOLUTION: This rear wheel toe angle control device 20 arranged in a variable rear wheel toe angle vehicle 1 with the rear wheel toe angle variably controlled and controlling the rear wheel toe angle θ includes; a steered angle sensor 14 detecting a front wheel steered angle δ<SB>f</SB>; a ground sensor 15 detecting the actual body slip angle β<SB>act</SB>; a target slip angle setting section 22 setting a target body slip angle β<SB>ideal</SB>based on the result (δ<SB>f</SB>) detected by the steered angle sensor 14; and a target rear wheel toe angle setting section 23 setting a target rear wheel toe angle based on a difference between the target slip angle β<SB>ideal</SB>and the actual body slip angle β<SB>act</SB>.
