Orang Kaya Indera Perba Jelai is a nobility title in Pahang Sultanate and one of the four highest ranking nobles below the monarch.
[2] The traditional pegangan ('fief') of the nobility is the land from Tanjung Lindung, the entire Jelai River basin (roughly covering the Cameron Highlands and Kuala Lipis constituencies), to the borders of Perak and Kelantan, excluding the Tembeling.
[3] It is the largest fief in size and the farthest in distance from the royal court in Pekan, thus making the Maharaja Perba the most powerful among the four major chiefs.
Their districts were subject to serahan; the obligation to buy, at exorbitant prices, goods the monopoly for the sale of which, in certain localities the ruler was in the habit of granting to one of his favourites.
The Pahang constitutional theory was that the Orang Besar Berempat and, to a lesser degree, the other chiefs were the foundation upon which the monarch's authority rested.
One of which, the oldest, was at one time in the possession of one of the eight nobles, Orang Kaya Maharaja Setia Raja Haji Wan Daud.
