John Raleigh Mott (May 25, 1865 – January 31, 1955) was an evangelist and long-serving leader of the Young Men's Christian Association (YMCA) and the World Student Christian Federation (WSCF). He received the Nobel Peace Prize in 1946 for his work in establishing and strengthening international Protestant Christian student organizations that worked to promote peace. He shared the prize with Emily Balch. From 1895 until 1920 Mott was the General Secretary of the WSCF. Intimately involved in the formation of the World Council of Churches in 1948, that body elected him as a lifelong honorary President. His best-known book, The Evangelization of the World in this Generation, became a missionary slogan in the early 20th century.
