Edward Thomas (1878 - 1917) was a British poet, essayist, and novelist. He is commonly considered a war poet, although few of his poems deal directly with his war experiences, and his career in poetry only came after he had already been a successful writer and literary critic. In 1915, he enlisted in the British Army to fight in the First World War and was killed in action during the Battle of Arras in 1917, soon after he arrived in France.

Nowadays there is a significant re-discovery of Thomas as a nature writer and poet.

The American poet Robert Frost, who was living in England at the time, in particular encouraged Thomas (then more famous as a critic) to write poetry, and their friendship was so close that the two planned to reside side by side in the United States. Frost's most famous poem, "The Road Not Taken", was inspired by walks with Thomas and Thomas's indecisiveness about which route to take.
