Who Are the American Recipients of the Nobel Peace Prize?

A total of 21 prizes have been given to U.S. citizens, the most recent of whom was President Obama.

Beginning with Theodore Roosevelt in 1906, there have been 18 American men and three American women who have been awarded the Nobel Peace Prize. In the case of the most recent American recipient, President Obama, the Nobel Committee recognized "his extraordinary efforts to strengthen international diplomacy and cooperation between peoples." Laureates have included not only presidents but secretaries of State, activists, and scientists.

Nobel prizes are bestowed in a variety of categories such as chemistry, literature, and economics; the Peace Prize specifically recognizes individuals who have made strides in negotiation, world organizing, disarmament, humanitarianism, or other efforts to advance peace.
