Riebeek East (Afrikaans: Riebeek-Oos) is a village in the Eastern Cape province of South Africa, set 39 km west of Grahamstown.

It is located in a hilly area, in the midst of game and sheep farming regions.

It was founded in 1842, and initially named Riebeek after Jan van Riebeeck, one year after the local church was built.

[2] It was erected on a part of the farm Mooimeisjesfontein,[3] that was subdivided and sold by the subsequent voortrekker leader Piet Retief.

[4] Retief's farm house is situated just east of the village, and has been declared a National heritage site.
