A Pair of Blue Eyes is a novel by English author Thomas Hardy, published in 1873, first serialised between September 1872 and July 1873. It was Hardy's third novel, but the first to bear his name on publication.

The book describes the love triangle between a young woman, Elfride Swancourt, and her two suitors from very different backgrounds. Stephen Smith is a socially inferior but ambitious young man who adores her and with whom she shares a country background. Henry Knight is the respectable, established, older man who represents London society.

Elfride finds herself caught in a battle between her heart, her mind and the expectations of those around her – her parents and society.

Thomas Hardy (1840-1928) was an English novelist and poet. A Victorian realist, in the tradition of George Eliot, he was also influenced both in his novels and poetry by Romanticism, especially by William Wordsworth.

Charles Dickens is another important influence on Thomas Hardy. Like Dickens, he was also highly critical of much in Victorian society, though Hardy focused more on a declining rural society.

Initially he gained fame as the author of such novels as Far from the Madding Crowd (1874), The Mayor of Casterbridge (1886), Tess of the d'Urbervilles (1891), and Jude the Obscure (1895). However, since the 1950s Hardy has been recognized as a major poet, and had a significant influence on The Movement poets of the 1950s and 1960s, including Phillip Larkin.

The bulk of his fictional works, initially published as serials in magazines, were set in the semi-fictional region of Wessex and explored tragic characters struggling against their passions and social circumstances. Hardy's Wessex is based on the medieval Anglo-Saxon kingdom and eventually came to include the counties of Dorset, Wiltshire, Somerset, Devon, Hampshire, and much of Berkshire, in south west England.
