PROBLEM TO BE SOLVED: To provide a brake fluid pressure control device for a vehicle capable of accurately estimating master cylinder pressure even if some wheels are in ABS control (or even if slipping). SOLUTION: The brake fluid pressure control device 100 for the vehicle estimates the estimated master cylinder pressure based on a wheel speed of each wheel of the vehicle. The brake fluid pressure control device has a deceleration calculation part 22 calculating the deceleration of each wheel of the vehicle, a temporary master cylinder pressure calculation part 23 calculating the temporary master cylinder pressure for each wheel based on the deceleration of each wheel calculated by the deceleration calculation part 22, and an estimated master cylinder pressure estimation part 24 estimating the minimum value as the estimated master cylinder pressure of this time among the temporary master cylinder pressure of each wheel calculated by the temporary master cylinder pressure calculation part 23.
