South Korean fencers have qualified a full squad each in the men's and women's team épée and women's team sabre by virtue of being the highest ranking team from Asia outside the world's top four in the FIE Olympic Team Rankings.

They were joined by four-time Asian men's foil champion Heo Jun as one of the two highest-ranked fencers from Asia outside the world's top eight qualified teams. Other fencers also featured London 2012 sabre champion Kim Ji-yeon and bronze medalist Jung Jin-sun in men's épée.

The fencing team was officially named to the South Korean roster for the Games on June 22, 2016.
