Djambala is a town and a commune,[1] administrative center of Djambala District and of Plateaux Department in the Republic of Congo.

Located near the Léfini Faunal Reserve, Djambala had a population of 24,734 in 2023, the date of the country's last official census.

It features a short dry season from June to August due to the influence of the Benguela Current reaching furthest north, and a lengthy wet season for the remaining nine months of the year.

Although temperatures are somewhat reduced by the city’s moderately high altitude, conditions are very warm and humid throughout the year even in the dry season.

In April 2007, a deal was signed with a Korean consortium to build a railway mainly for timber traffic from the main port to Djambala.
