To obtain a hydraulic pressure control unit and a straddle-type vehicle brake system, each of which can answer a request for downsizing.The straddle-type vehicle brake system has a hydraulic circuit that includes: a primary channel through which brake fluid in a master cylinder is delivered to a wheel cylinder; a secondary channel through which the brake fluid in the wheel cylinder is released to a primary channel intermediate portion; and a supply channel that supplies the brake fluid to a secondary channel intermediate portion. In a state where a surface on which a motor 28 of a base body 51 in the hydraulic pressure control unit is vertically provided is seen from the front, an opening for a first valve 31 that controls a flow rate on the wheel cylinder side of the primary channel intermediate portion and an opening for a second valve 32 that controls a flow rate on an upstream side of the secondary channel intermediate portion overlap a first straight line L1, and an opening for a third valve 35 that controls a flow rate on the master cylinder side of the primary channel intermediate portion and an opening for a fourth valve 36 that controls a flow rate of the supply channel overlap a second straight line L2 that crosses the first straight line L1 at a right angle.
