Tanzanian general election, 1970

General elections were held in Tanzania on 30 October 1970. The country was a one-party state at the time, with the Tanganyika African National Union as the sole legal party on the mainland, and the Afro-Shirazi Party was the only party in Zanzibar. For the National Assembly election there were two candidates from the same party in each of the 106 constituencies, whilst the presidential election was effectively a referendum on TANU leader Julius Nyerere's candidacy.

Voter turnout was 70.1% in the presidential election and 66.6% in the National Assembly election.
