A Nobel Committee is a working body responsible for most of the work involved in selecting Nobel Prize laureates. There are five Nobel Committees, one for each Nobel Prize.
Four of these committees (for prizes in physics, chemistry, physiology or medicine, and literature) are working bodies within their prize awarding institutions, the Royal Swedish Academy of Sciences, Karolinska Institutet, and the Swedish Academy. These four Nobel Committees only propose laureates, while the final decision is taken in a larger assembly. This assembly is composed of the entire academies for the prizes in physics, chemistry, and literature, as well as the 50 members of the Nobel Assembly at the Karolinska Institute for the prize in physiology or medicine.
The fifth Nobel Committee is the Norwegian Nobel Committee, responsible for the Nobel Peace Prize. This committee has a different status since it is both the working body and the deciding body for its prize.
