A tire air pressure monitoring system of the present invention includes: a data acquisition unit (101) that acquires tire air pressure data at each fixed detection period; a storage unit (102) that stores newly acquired air pressure data P(0), and air pressure data P(1) to P(N) acquired 1 to N periods prior to the air pressure data P(0); a determination unit that determines a state in which air pressure has decreased, on the basis of air pressure data; and a communication unit (transmitter 150) that transmits a determination result of the determination unit to an external device, in which the determination unit compares each piece of the air pressure data P(1) to P(n) with the air pressure data P(0) to calculate decrease values, compares the decrease values with a preset first threshold value (th1), and determines that tire air pressure is decreasing when at least one decrease value is greater than or equal to the first threshold value.
