Thabo Mvuyelwa Mbeki (pronunciation: [tʰaɓɔ mbɛːkʼi]; born 18 June 1942) is a South African politician who served two terms as the second post-apartheid President of South Africa from 14 June 1999 to 24 September 2008. He is also the brother of Moeletsi Mbeki. On 20 September 2008, he announced his resignation after being recalled by the African National Congress's National Executive Committee, following a conclusion by Judge Nicholson of improper interference in the National Prosecuting Authority (NPA), including the prosecution of Jacob Zuma for corruption. On 12 January 2009, the Supreme Court of Appeal unanimously overturned Judge Nicholson’s judgment but the resignation stood.

Thabo Mbeki was the executive face of government in South Africa from 1994. During his time in office the economy grew at an average rate of 4.5% per annum. Mbeki created employment in the middle sectors of the economy and oversaw a fast growing black middle class with the implementation of BEE. This growth exacerbated the demand for trained professionals strained by emigration due to violent crime, but failed to address unemployment amongst the unskilled bulk of the population. He attracted the bulk of Africa’s Foreign Direct Investment (FDI) and made South Africa the focal point of African growth. He was the architect of NEPAD whose aim is to develop an integrated socio-economic development framework for Africa. He also oversaw the successful building of economic bridges to BRIC (Brazil, Russia, India and China) nations with the eventual formation of the India-Brazil-South Africa (IBSA) Dialogue Forum to "further political consultation and co-ordination as well as strengthening sectoral co-operation, and economic relations".
