Sultan Ahmad Shah I ibni Almarhum Sultan Mansur Shah (died 1519) was the second Sultan of Pahang from 1475 to 1495. He succeeded his younger brother, Muhammad Shah as sultan after the latter's death by poisoning in 1475. During his reign, relations between Pahang and its Malaccan overlord, deteriorated greatly, as a result of Sultan Ahmad's resentment towards his half-brother Sultan Alauddin Riayat Shah of Malacca. Under Sultan Ahmad's rule, Pahang became increasingly unstable with Sultan Ahmad abdicating around 1495, in favour of his son, Raja Mansur.
