Nobel Peace Prize: nomination and decision

A Nobel Peace Prize nomination is not an award. It begins a review process.

Submissions close January thirty-first. Nominations are checked for validity before reaching the Nobel Committee.

The Committee shortlists candidates. Independent experts provide reports, while repeated discussions narrow the field.

The Norwegian Nobel Committee makes the final decision. The winner is announced in October.
