Pagar Alam (sometimes written as Pagaralam, Jawi: ڤاݢر عالم‎), is a city in South Sumatra, Indonesia. It was formerly part of Lahat Regency, from which it was separated as an independent city on 21 June 2001; before being established as an independent city, Pagar Alam was an administrative city within Lahat Regency. It has an area of 633.66 km and a population of 126,181 at the 2010 Census and 143,844 at the 2020 Census; the official estimate as at mid 2023 was 150,881 (comprising 77,147 males and 73,734 females).

Pagar Alam is located by the Bukit Barisan Mountains, at the foot of Mount Dempo (Gunung Dempo), a volcano and the highest mountain in South Sumatra, which towers to a height of 3,159m to the west of the town. It is 298 km southwest from the province's capital city of Palembang and 60 km southwest of the town of Lahat. The city is bounded by Bengkulu Province to the south, Jarai District to the north, Kota Agung District to the east and Tanjung Sakti Pumi District to the west. Pagar Alam is one of the main suppliers of vegetables in Palembang. Its location in the highland makes the city slightly cooler than many of the other South Sumatra cities; this, together with its astounding landscape, makes the city one of the main tourist destinations in South Sumatra and it is often visited by local tourists, especially from Palembang. Currently, the city is led by Alpian Maskoni as the mayor of the city.

Pagar Alam is located by the Bukit Barisan Mountains, at the feet of Mount Dempo. It is situated on the Pasemah Plateau, an extensive fertile highland plain which is surrounded by mountains. It is notable for ancient stone megaliths which surround the town on all sides and are the remnants of a Bronze Age culture. Much of the soil in the city consists of latosol and andisol with rugged and hilly topography. The soil in this city is classified as soil with high fertility (class I).

In 2000, Pagar Alam's population was only 112,025 and it increased to 126,181 ten years later, and 143,844 after a further decade. One of the factors in the population increase has been the settlement of migrants who want to live in this city. Beside the city's native inhabitants, the Malay (Besemah), the city population also consists of several other groups, such as the Javanese, Minang, Batak, Chinese, Arabs, and Indians.
