Kubu Island (Ga'nnyo) is a dry granite rock island located in the Makgadikgadi Pan area of Botswana. The island is located a few kilometers away from Orapa and Letlhakane mining towns and can be accessed through Mmatshumo in the Boteti district. The entire island is a national monument, and is considered a sacred site by the indigenous people of the area.

It is accessible by four wheel drive vehicle and has basic camping facilities. The campsite is run for the benefit of the local population. Top Gear presenter Jeremy Clarkson described the island as "just about the most astonishing place I've ever been" on the Botswana Special episode.
