Willem Cornelis Janse van Rensburg

Willem Cornelis Janse van Rensburg (16 May 1818 – 13 August 1865) was the second President of the Executive Council of the South African Republic, from 18 April 1862 until 10 May 1864.

He was born near the town of Beaufort West, the son of Hendrik Janse van Rensburg and his second wife, Martha Magdalena Oosthuizen.

In February 1860, during Pretorius's absence, the Volksraad offered Janse van Rensburg the post of State President, which he refused.

Following substantial political maneuvering, Janse van Rensburg was elected as the second president of the ZAR in April 1863.

However, in August 1974, Janse van Rensburg and his wife were disinterred and reburied at the Heroes' Acre Cemetery in Pretoria.
