The present invention relates to a crash pad upper mounting bracket which is installed between an HVAC (heating, ventilation and air conditioning) to which a connecting duct of a vehicle is connected, and a crash pad, the crash pad upper mounting bracket including: a base which is installed at a lower side of the crash pad; and a mounting portion which protrudes from the base so as to press one region of the connecting duct. Accordingly, the crash pad upper mounting bracket presses the connecting duct so as to maintain airtightness between the HVAC and the connecting duct, thereby preventing deterioration in air conditioning performance.
