Tanzania Tourist Board is a government parastatal organization that was legally established by Tanzania Tourist Board Act, CAP 364 R.E. 2002 as amended by Act No. 18 of 1992. TTB was formed after the disbandment of the Tanzania Tourist Corporation (TTC). The history of TTB begins when Tanzania got its independence in 1961, the government 1962 created Tanganyika National Tourist Board (TNTB) and decided subsequently that to improve its performance in the Tourism industry, National Development Corporation (NDC) 1964 was assigned to develop hotels in different areas in the country. Between 1965 and 1968 Ngorongoro Crater, Lobo Lodge in Serengeti, Seronera Wildlife Lodge, Mikumi Lodge in Mikumi area, Mafia Island Fishing Lodge in Mafia Island, The Kilimanjaro Hotel, and Bahari Beach Hotel in Dar-es-salaam were developed and established. Apart from owning and managing the Hotels and lodges, TTC was also mandated to manage and supervise Tanzania Wildlife Corporation, the organization that managed wildlife hunting in Tanzania as well as State Travel services (STS). STS opened tourism offices (marketing outlets) in Frankfurt (Germany), Milan (Italy), London (England), and New York (United States of America).

Between the 1980s and 1990s under the economic reforms in Tanzania, TTC was dissolved and Tanzania Tourist Board (TTB) was established by TNTB Act No.18 of 1992 after the amendment of the Tanganyika National Tourist Board Act. Under the reforms, all the hotels and State Travel Services Limited under TTC were privatized. Privatized hotels and STS were the main sources of funds that were invested to promote and advertise tourism in and outside Tanzania. TTB was left with the responsibility of promoting and marketing tourism and its source of funds remained government subvention under the parent ministry responsible for tourism.
