John Keats (pronounced /ˈkiːts/; 31 October 1795 – 23 February 1821) was the last born of the English Romantic poets and, at 25, the youngest to die. Along with Lord Byron and Percy Bysshe Shelley, he was one of the key figures in the second generation of the Romantic movement, despite the fact that his work had been in publication for only four years before his death. During his life, his poems were not generally well received by critics; however, his reputation grew and he held significant posthumous influence on many later poets, including Alfred Tennyson and Wilfred Owen.

The poetry of Keats is characterised by sensual imagery, most notably in the series of odes. Today his poems and letters are considered as among the most popular and analysed in English literature.
