Lesego Benjamin Phehla, a student at Tshwane University of Technology in the capital Pretoria, was hit by a car and killed there on Thursday, the presidency said in a statement.
Police in Pretoria had used tear gas and stun grenades to disperse hundreds of students gathered outside President Jacob Zuma's offices as protests turned violent, with some students hurling sticks and bottles at police.
Weeks of demonstrations calling for the scrapping of university fees, prohibitive for many black students, have highlighted frustration at enduring inequalities in South Africa more than two decades after the end of white minority rule.
