General Johannes Jacobus Geldenhuys (Jannie, born 1935) was a South African military commander. He joined the South African Army as an infantryman in 1954. He commanded the South West Africa Command from 1977 to 1980 and was briefly the first GOC of the South West Africa Territory Force in 1980. He was Chief of the South African Defense Force from 1985 to 1990 and a member of the State Security Council.
Born in Kroonstad, Free State, he is widely regarded as one of the leading military commanders South Africa has ever had. Geldenhuys earned acclaim for his diplomatic and negotiating skills in South West Africa (Namibia) during negotiations towards an internationally acceptable solution that would lead to independence. In 2001 Geldenhuys was denied amnesty by the Truth and Reconciliation Commission (TRC) for the role he played in an attempt to release Charles Sebe from a Ciskeian jail in 1986.
