The municipality name comes from tupi, meaning "great river of axes", through the junction of yî (axe) e paranã (sea, great river). It is a reference to the great amount of rocks in the river looking like indigenous axes.^[5][6] The municipality is also known as the Heart of Rondônia, due to the central city location and the existence of a heart shaped island, located in the confluence of the Machado and Urupá River.

Located in central Rondônia, the city attracted many settlers from the 1970s onward. As a result of corruption, lawlessness and a general lack of regulation, Ji-Paraná has been at the centre of Rondônia's extreme deforestation, which today extends up to the border with Bolivia. The area between Ji-Paraná and Porto Velho, the regional capital 373 km away, is now largely deforested. The deforestation expands along smaller illegally built roads stemming from the BR-364 highway.

The city is served by José Coleto Airport.

The municipality contains part of the 346,861 hectares (857,110 acres) Jaru Biological Reserve, a fully protected conservation unit created in 1984.^[7]

Isaú Raimundo da Fonseca is the city's current mayor, his term expires in 2024.^[8]
