"Ozymandias" is a sonnet written by the English Romantic poet Percy Bysshe Shelley (1792–1822). It was first published in the 11 January 1818 issue of The Examiner of London. The poem was included the following year in Shelley's collection Rosalind and Helen, A Modern Eclogue; with Other Poems, and in a posthumous compilation of his poems published in 1826.

Percy Bysshe Shelley was a British writer who is considered as one of the major English Romantic poets. A radical in his poetry as well as in his political and social views, Shelley did not achieve fame during his lifetime, but recognition of his achievements in poetry grew steadily following his death, and he became an important influence on subsequent generations of poets, including Robert Browning, Algernon Charles Swinburne, Thomas Hardy, and W. B. Yeats. American literary critic Harold Bloom describes him as "a superb craftsman, a lyric poet without rival, and surely one of the most advanced sceptical intellects ever to write a poem."
