General elections were held in Zambia on 19 December 1968 to elect the National Assembly and President. The first post-independence polls saw incumbent Kenneth Kaunda retain his post as president, whilst his United National Independence Party, the only party to field candidates in all 105 constituencies, won 81 of the 105 seats in the National Assembly. Voter turnout was 82.5% in the parliamentary election, but 87.1% in the presidential election.
The only other contestants in the National Assembly elections were the Zambian African National Congress (73 candidates), and three independents. The United Party, which had been established in 1966, was banned in 1968, with many of its members absorbed by the ZANC. The election campaign was marred by violence, with UNIP members in Northern and Luapula Provinces blocking ZANC candidates from lodging nomination papers, resulting in 30 UNIP candidates running unopposed. Nevertheless, the election saw a swing towards the ZANC; four ministers lost their seats.
In 1972, the Kaunda government announced its intention to make UNIP the only legally permitted party in the country. This was formalised with a new constitution that was promulgated in August 1973. As a result, the 1968 elections were the last multiparty elections held in Zambia until 1991.
