The invention discloses a cabin pressure regulator. The cabin pressure regulator comprises a cabin outflow valve, a low-altitude overbottom pressure control mechanism, an absolute pressure control mechanism, a high-altitude overbottom pressure control mechanism and a three-way change-over switch. The absolute pressure control mechanism and the high-altitude overbottom pressure control mechanism are directly or indirectly connected with the three-way change-over switch, the three-way change-over switch is directly or indirectly connected with the cabin outflow valve, the low-altitude overbottom pressure control mechanism is arranged in front of or at back of the three-way change-over switch, or the low-altitude overbottom pressure control mechanism is arranged at back of the absolute pressure control mechanism. According to the cabin pressure regulator, by means of the low-altitude overbottom pressure control mechanism, the function for controlling cabin low-altitude overbottom pressure is achieved through the cabin pressure regulator.
