The National Council of Provinces (NCOP) is the upper house of the Parliament of South Africa under the (post-apartheid) constitution which came into full effect in 1997. It replaced the former Senate, but is very similar to that body, and to many other upper houses of legislatures throughout the world, in that its purpose is to represent the governments of the provinces, rather than directly representing the people.

An upper house is one of two chambers of a bicameral legislature, the other chamber being the lower house. The house formally designated as the upper house is usually smaller and often has more restricted power than the lower house. A legislature composed of only one house is described as unicameral.
