Sir Robert Nelson Kotzé (13 April 1870 – 14 March 1953) was a South African mining engineer, politician, and academic administrator.

Kotzé was knighted in 1918 for his contributions to the mining industry, particularly for addressing the dust problem (silicosis) in the Witwatersrand gold mines. He was awarded the Institution of Mining and Metallurgy's gold medal in 1925 for his work in promoting South Africa's natural resources.

Early life and education Robert Nelson Kotzé was born in 1870 in Cape Town, Cape Colony, to Petrus Johannes Kotzé, a prominent figure who owned the Leeuwenhof estate and served as mayor of Cape Town, and Elizabeth Jacoba Blanckenberg, from a family with ties to the Dutch Reformed Church. His older brother, Sir John Gilbert Kotzé, was a distinguished jurist. The Kotzé family traced its South African roots to Jan Kotze, a German settler who arrived at the Cape in 1691.
