Tanzania Olympic Committee (TOC) was originally established in 1957 as Tanganyika Commonwealth Games Association (TCGA). It was constituted under this name in order to participate at the 1962 Australia Commonwealth Games in Perth, Australia which Tanzania (by then Tanganyika) participated for the first time as an independent sovereign state. Tanganyika became independent in December 9th 1961.
The name TCGA changed to Tanganyika Olympic Committee in 1963 in order to qualify and participate at the 1964 Olympic Games which were held in Tokyo, Japan.
Following the Union of Tanganyika and Zanzibar in 1964 to form Tanzania the name of the Committee changed again to the present format of Tanzania Olympic Committee (TOC) in 1967.
In 1968 Tanzania participated in the Mexico Olympic Games. Tanzania had to apply for membership of the IOC in order to take part at the Mexico City Olympic Games. TOC was formally registered by the National Sport Council (NSC) on the 8th December, 1989 under the NSC Certificate No. 4802
