There is provided a hydraulic control device that improves the reliability. The hydraulic control device includes a rear-side connection fluid path, a front-side connection fluid path, a first discharge fluid path, a first hydraulic source, a second discharge fluid path, a second hydraulic source, and a shutoff valve. The rear-side connection fluid path connects a master cylinder with a rear-side wheel cylinder. The front-side connection fluid path connects the master cylinder with a front-side wheel cylinder. The first discharge fluid path is connected to the rear-side connection fluid path and to the front-side connection fluid path. The first hydraulic source is configured to discharge a brake fluid to the first discharge fluid path. The second discharge fluid path is connected to the front-side connection fluid path at a position between a connecting position of the first discharge fluid path and the front-side wheel cylinder. The second hydraulic source is configured to discharge the brake fluid to the second discharge fluid path. The shutoff valve is placed between the connecting position of the first discharge fluid path and a connecting position of the second discharge fluid path in the front-side connection fluid path.
