Bartica is a town located on the west bank of the Essequibo River in Cuyuni-Mazaruni (Region 7), at the confluence of the Cuyuni and Mazaruni Rivers with the Essequibo River in Guyana. It is the regional capital of Cuyuni-Mazaruni.

Considered the "Gateway to the Interior", the town has a population of 8,004 as of 2012, and is the launching point for people who work in the bush, mining gold and diamonds.

The town developed from an Anglican missionary settlement, established in 1837, and consecrated in 1843. The name Bartica comes from an indigenous word meaning "red earth", abundant in the area. According to the Georgetown Daily Chronicle of July 30, 1892, the ornithologist Whitely died in his camp on the Annie Scapy River near Bartica. He was in a state of delirium from malaria and also depressed by the loss of his bird hunting haul when his boat sank. This was probably the reason why he eventually shot himself.

Bartica has two secondary school Bartica Secondary and Three Miles Secondary and three primary schools, St. Anthony's Primary and St. John-the-Baptist and Two Miles Primary. There are several other primary schools in the surrounding riverine communities.

The region 7 hospital is located in Bartica and is known for having implemented the country’s first electronic Health Information System in 2005, developed by Peace Corps volunteers Geoffrey Thompson and Jason Knueppel.
