MacCarthy Island, commonly known today by the town name Janjanbureh, is an inhabited island in the middle reaches of the Gambia River in the Central River Division. It is the site of a market town that served as a colonial administrative and trading post.

The island town contains 19th-century colonial-era structures and remains a local centre for administration, commerce and river transport. Visitors encounter a compact townscape with markets and waterfront activity rather than tourist infrastructure.

The island was settled and developed during the period of British influence in the region as a riverside trading post and administrative location and has continued as a local hub for communities along the Gambia River.

Geographically MacCarthy Island sits within the central Gambia River corridor, upstream from the river mouth and connected to river transport routes that link it to surrounding settlements.

  • Town: The island hosts the town of Janjanbureh, historically known as Georgetown, which contains colonial-era buildings and local markets.
  • Access and function: Accessible by river transport and serves as an administrative and trading centre for the surrounding riverine districts.
