The 51st National Conference of the African National Congress (ANC) was held at the University of Stellenbosch in Stellenbosch, Western Cape, from 16 to 20 December 2002, during the ANC's 90th anniversary. President Thabo Mbeki was re-elected to the party presidency and, notably, there was no change in other five top leadership positions except for Deputy Secretary General. There was also little competition for other spots on the National Executive Committee (NEC). This ANC conference has thus been called "the quietest in its history."

Thabo Mvuyelwa Mbeki is a South African politician who served as the second president of South Africa from 14 June 1999 to 24 September 2008, when he resigned at the request of his party, the African National Congress (ANC). Before that, he was deputy president under Nelson Mandela from 1994 to 1999.
