An automatic caster control apparatus for a vehicle is provided to automatically control the caster during a vehicle rolling status such that the vehicle is able to go straight on. An automatic caster control apparatus for a vehicle comprises an angle sensor(110) for detecting a steering angle, an actuator(120) rotating a strut(14) to control the caster, and a controller(130). The controller drives the actuator when the measured steering angle exceeds a predetermined range. The actuator is provided on the struts located at both front wheels and is individually or simultaneously driven by the controller. The actuator includes a pair of hydraulic cylinders installed at the front and rear of the struts, a hydraulic pack supplying and returning oil to the hydraulic cylinders, and a pair of hydraulic pipelines connecting the hydraulic cylinders with the hydraulic pack.
