The Ssese Islands are an archipelago of eighty-four islands in the northwestern part of Lake Nalubaale in Uganda. The islands are coterminous with the Kalangala District in southern Central Uganda, which does not have any territory on mainland Uganda.

The islands lie in two main groups. The south west can be referred to as the Bugala Group, after Bugala Island, the largest in the archipelago. The northeastern group can be referred to as the Koome Group, after Koome Island, the largest in that group. The two groups are separated by the Koome Channel. Other islands in the Bugala Group include: Bubeke, Bubembe, Bufumira, Bugaba, Bukasa, Buyova, Funve and Serinya. The main islands in the Koome Group include: Damba, Koome and Luwaji.
