The Perak River (Malay: Sungai Perak) is the second longest river in Peninsular Malaysia after the Pahang River.
A number of towns are on the banks of the river including the royal town of Kuala Kangsar. Most of the settlements in what is today Perak were situated near the river until the 19th century, when tin deposits were discovered elsewhere, most notably Ipoh.
Perak (Malay pronunciation: [peraΚ]; Perak Malay: Peghok) is a state of Malaysia on the west coast of the Malay Peninsula. Perak has land borders with the Malaysian states of Kedah to the north, Penang to the northwest, Kelantan and Pahang to the east, and Selangor to the south. Thailand's Yala and Narathiwat provinces both lie to the northeast. Perak's capital city, Ipoh, was known historically for its tin-mining activities until the price of the metal dropped, severely affecting the state's economy. The royal capital remains Kuala Kangsar, where the palace of the Sultan of Perak is located. The state's population is 2,000,000.
Perak has diverse tropical rainforests and an equatorial climate. The state's main mountain ranges are composed of the Titiwangsa, Bintang and Keledang Ranges, where all of them are part of the larger Tenasserim Hills system that connects Myanmar, Thailand and Malaysia.
