Nicholas Folker (born October 26, 1976) is a South African former swimmer, who specialized in sprint freestyle events.

[2][3] Folker made his own swimming history at the 1999 Summer Universiade in Palma de Mallorca, Spain, where he earned a bronze medal in the 100 m freestyle at 50.77, finishing behind Russia's Denis Pimankov and Italy's Mauro Gallo.

[7][8] First, he teamed up with Roland Mark Schoeman, Brendon Dedekind, and deaf-mute Terence Parkin in the 4 × 100 m freestyle relay.

During the prelims race, he swam a freestyle leg in the same heat with a scintillating anchor of 49.53 to deliver a fourth-place finish and thirteenth overall for the South Africans in 3:42.44.
