Tourism in Zanzibar includes the tourism industry and its effects on the islands of Unguja (known internationally as Zanzibar) and Pemba in Zanzibar a semi-autonomous region in the                      United Republic of Tanzania. Tourism is the top income generator for the islands, outpacing even the lucrative agricultural export industry and providing roughly 25% of income. The main airport on the island is Zanzibar International Airport, though many tourists fly into Dar es Salaam and take a ferry to the island.

The Government of Zanzibar plays a major role in promoting the industry, with the official government tourist page stating that its goal regarding tourism is to “become one of the top tourism destinations of the Indian Ocean, offering an up market, high quality product across the board within the coming 17 years.” Zanzibar Commission for Tourism recorded more than doubling the number of tourists from the 2015/2016 fiscal year and the following year, from 162,242 to 376,000.

The increase in tourism has led to significant environmental impacts and mixed impacts on local communities, which were expected to benefit from economic development but in large part have not. Communities have witnessed increasing environmental degradation, and that flow of tourists has reduced the access of local communities to the marine and coastal resources that are the center of tourist activity.
