Muller Conrad "Billy" Rautenbach (born 23 September 1959) is a Zimbabwean business magnate, whose more than 150 ventures have included companies involved in transport, cobalt and platinum mining, and biofuel production, primarily in Africa. The 2022 Data Leaks at Credit Suisse appeared to confirm allegations – for which he had faced American and European sanctions in earlier years – that Rautenbach used the proceeds from a mining deal to support the ZANU-PF regime of dictator Robert Mugabe, during the latter's repressive 2008 election campaign in Zimbabwe. From 1999 to 2009, Rautenbach was a fugitive from fraud and corruption charges in South Africa.
