PURPOSE: A automatic hydraulic parasol with an improved structure is provided to ease opening/closing the parasol both indoor and outdoor, and to improve strength and safety of the parasol. CONSTITUTION: The automatic hydraulic parasol includes a plate(1) for fixing the upper parasol frame, a parasol base(2), a lower parasol base connecting plate(3), a parasol frame(4), a central axis cylindrical iron pipe(5), a shaft(6), a cylinder(7), a hydraulic hose(8), a control lever(9), a hydraulic pump(10), an accelerated rotational axis(11), a hydraulic motor(12), a hydraulic tank(13), a ground concrete(14), a bolt(15), a nut(16), and a parasol top(17). When the motor(12) starts driving, the pump(10) rotates and the tank(13) generates a hydraulic pressure that is eventually transmitted to the cylinder(7).
