This paper is a report on epibenthic algae identified in water samples recovered from Kahuzi-Biega National Park streams. The samples were collected during dry season (July-August 2007) from 10 streams. Altogether, some 170 species with 9,872 individuals have been identified, belonging to 6 algal groups containing 61 genera. Bacillariophyceae with 3,550 individuals (61 species, 20 genera) formed the most abundant group followed by Cyanophyceae with 2,551 individuals (47 species, 12 genera) and Chlorophyceae with 1,685 individuals (30 species, 15 genera). This algal community is very diversified and balanced (Shannon-Weiner index varied between 4.44-4.67, Species Diversity between 15.81-13.31 and Equitability between 0.97-0.99). The higher number of species (114 species, 55 genera) was recorded at station MV and the lesser number (91 species, 51 genera) at station MG.
