Robert Traill Spence Lowell IV (; March 1, 1917 – September 12, 1977) was an American poet. He was born into a Boston Brahmin family that could trace its origins back to the Mayflower. His family, past and present, were important subjects in his poetry. Growing up in Boston also informed his poems, which were frequently set in Boston and the New England region. The literary scholar Paula Hayes believes that Lowell mythologized New England, particularly in his early work.
