James Allen (November 28, 1864 - 1912) was a philosophical writer of British nationality, known for his inspirational books and poetry. His works have had a lasting influence on the New Thought Movement.

Born in Leicester, England, he left school to work full-time in several British manufacturing firms to help support the family. At 38, inspired by the writings of Leo Tolstoy, he moved to a small cottage in Ilfracombe, Devon, England to pursue a simple life of contemplation. There he wrote for nine years, producing 19 works. He also edited and published a magazine, ‘The Light of Reason.’

Allen’s most famous book, As a Man Thinketh, was published in 1902. It is now considered a classic self-help book.

James Allen’s books illustrate the use of the power of thought to increase personal capabilities. Although he never achieved great fame or wealth, his works continue to influence people around the world.
