Sir John Collings Squire (2 April 1884 – 20 December 1958) was a British poet, writer, historian, and influential literary editor of the post-World War I period. His writings mostly discuss common experiences.
Born in Plymouth, he was educated at Blundell's School and St. John's College, Cambridge. He was one of those published in the Georgian poetry collections of Edward Marsh. His own Selections from Modern Poets anthology series, launched in 1921, became definitive of the conservative style of Georgian poetry.
