The Norwegian Nobel Committee will now choose a name among the nominees.
They include US soldier Bradley Manning, who sent thousands of secret documents to Wikileaks, and 15-year-old Pakistani schoolgirl Malala Yousafzai, who was shot in the head by Taliban militants while on her way home from school, reports news agency AP.
The Nobel Peace Prize is awarded by a committee chosen by Norwegian parliamentarians. The other Nobel prizes are decided here in Stockholm.
Last year's peace prize went to the European Union.
