Air Tanzania Company Limited (ATCL) (Swahili: Kampuni ya Ndege Tanzania) is the flag carrier airline of Tanzania based in Dar es Salaam with its hub at Julius Nyerere International Airport. It was established as Air Tanzania Corporation (ATC) in 1977 after the dissolution of East African Airways and has been a member of the African Airlines Association since its inception. The airline was wholly owned by the Tanzanian Government until 2002 when it was partially privatised as per the directive of the Bretton Woods Institutions to implement the country's Structural Adjustment Program. The government therefore reduced its shareholding to 51 percent and entered into a partnership with South African Airways.

The partnership lasted for about four years and had accumulated losses of more than Tsh 24 billion (US$19 million). The government repurchased the shares in 2006 and it is once again a wholly owned government company. Over the years, it has served a variety of domestic, regional, and intercontinental destinations. Despite being the national airline, its market share has deteriorated over the years from 19.2 percent in 2009 to 0.4 percent in 2011.

Air Tanzania Corporation (ATC) was established on 11 March 1977 after the break-up of East African Airways (EAA), which had previously served the region. The liquidation of EAA followed its accumulation of US$120 million of debt. Prior to its formation, EAA had served the region since 1946 during the British rule of East Africa. After the dissolution of EAA, Kenya and Uganda also formed its own flagcarriers: Kenya Airways and Uganda Airlines respectively.It was wholly owned by the government.
