The Mazaruni River is a tributary of the Essequibo River in northern Guyana. Its source is in the remote western forests of the Pakaraima Mountains and its confluence with the Cuyuni River is near Bartica. As it descends from the Guiana Highlands the river runs south-east, past Issano, then northward to Bartica. The river is a source of alluvial gold.

Course
The Mazaruni River drops down from each Roraima plateau through three steep sided canyons with many picturesque sets of falls. The first set is Chai-chai Falls. The next is near village of Imbaimadai and the last set is below the village of Kamarang where the Mazaruni River tumbles through last few major falls, the first of which is a few kilometres long gutter known as Chitigokein Falls, which finishes in Coffy pool, a deep pool named after Mehir “Cousin Body” Coffy, one of the last "Porknockers" (these are small diamond and gold miners) of Guyana.The term "Porknockers" comes from the old prospectors having to carry in all their food one of which was salt pork which attracted flies and had to be knocked regularly to keep flies away. According to legend, during the 1950s, Coffy was diving in the river for diamonds when he got the bends, due to overstaying below and rapid decompression.
After few kilometres of relatively calm water, the last set of great Mazaruni River Falls begin. The first falls is the Aruwai Falls and the last is the Peaima Falls.
Soon after Peaima Falls, the river, which was flowing north-south, turns east-south-east. It passes the Issineru River mouth on the left bank, with the Amerindian village, Issineru, on the other bank. Then, over the lowlands of greenstones of Precambrian Guiana Shield, the Meamu River, Kurupung River and Eping River join the Mazaruni River. Together, these rivers serve to drain the highlands of the Merume Mountains.
Next, the Mazaruni River flows past Oranapai Rapids, Kamakusa Landing, the mouth of Merume River, Banana Landing, Tiboku Rapids, the mouth of Equeribisi River, Issano Landing, the mouth of the Puruni River, Kaburi rapids, Marshal Falls, the last set of rapids, Itabali Landing, the mouth of the Cuyuni River, then, near the village of Bartica, finishes into the Essequibo River, the largest river of Guyana.
Fauna
The iron hydroxide stained brown waters of Mazaruni are home to many fish. The most abundant are the large and dangerous black electric eels (numfish), piry (relative of piranha cutleback), haimara, and baiara. However, the most famous fish is lau-lau, with specimens weighing up to 200 kg. Lau-lau lives in deep pools of Mazaruni River hunting in the night. Mazaruni River waters are also home to a largest water snake, anaconda, locally known as water kamudi. Large herds of wild pigs, peccaries, sometimes as large as a few hundred, live on swampy flat of Mazaruni River. They are very dangerous since they are known to attack humans. The only escape is up the large tree. Pumas and the much smaller ocelot are also found there but rarely seen since they hunt at night. Many monkeys, of which the howling monkey is the noisiest, inhabit tree tops, sharing the space with many types of birds. Pairs of Red, yellow or bleu Macaws, united for life, often can be seen to fly by.
Flora
The Mazaruni River flows over three distinct habitats; the flat tops of Roraima Plateau, known in Venezuela as “tepuis”, the lower two plateaus and the low lands. Each habitat is characterised by its own vegetation. The upper one is a fantastic land of rain swept sandstone eroded into fantastic forms with exotic plants trying to survive this inhospitable land of denuded rocks. The middle one is mainly savannas with bands of single canopy jungle, the lowest is a triple canopy jungle. Exotic orchids are found in last two habitats.
