Wuthering Heights is the only novel by the English author Emily Brontë, initially published in 1847 under her pen name "Ellis Bell". It concerns two families of the landed gentry living on the West Yorkshire moors, the Earnshaws and the Lintons, and their turbulent relationships with the Earnshaws' foster son, Heathcliff. The novel, influenced by Romanticism and Gothic fiction, is considered a classic of English literature.

Wuthering Heights was accepted by publisher Thomas Newby along with Anne Brontë's Agnes Grey before the success of their sister Charlotte Brontë's novel Jane Eyre, but they were published later. The first American edition was published in April 1848 by Harper & Brothers of New York. After Emily's death, Charlotte edited a second edition of Wuthering Heights, which was published in 1850.

Though contemporaneous reviews were polarised, Wuthering Heights has come to be considered one of the greatest novels written in English. It was controversial for its depictions of mental and physical cruelty, including domestic abuse, and for its challenges to Victorian morality, religion, and the class system. It has inspired an array of adaptations across several media.

In 1801, Mr Lockwood, the new tenant at Thrushcross Grange in Yorkshire, pays a visit to his landlord, Heathcliff, at his remote moorland farmhouse, Wuthering Heights. There he meets a reserved young woman (later identified as Cathy Linton), Joseph, a cantankerous servant, and Hareton, an uneducated young man who speaks like a servant. Everyone is sullen and inhospitable. Snowed in for the night, Lockwood reads diary entries of the former inhabitant of his room, Catherine Earnshaw, and has a nightmare in which a ghostly Catherine begs to enter through the window. Awakened by Lockwood's fearful yells, Heathcliff is troubled.

Lockwood later returns to Thrushcross Grange in heavy snow, falls ill from the cold and becomes bedridden. While he recovers, Lockwood's housekeeper, Ellen "Nelly" Dean, tells him the story of the strange family.

Thirty years earlier, in 1771, the Earnshaws live at Wuthering Heights with their two children, Hindley and Catherine, and a servant—Nelly herself. Returning from a trip to Liverpool, Earnshaw brings home an orphan whom he names Heathcliff. Heathcliff's origins are unclear but he is described as "like a gipsy" and, possibly, a Lascar or an American or Spanish castaway. Earnshaw treats the boy as his favourite. His own children he neglects, especially after his wife dies. Hindley beats Heathcliff, who gradually becomes close friends with Catherine.

Hindley departs for university, returning as the new master of Wuthering Heights on the death of his father three years later. He and his new wife Frances force Heathcliff to live as one of their servants and subject him to much verbal and emotional abuse.

Edgar Linton and his sister Isabella live nearby at Thrushcross Grange. Heathcliff and Catherine spy on them out of curiosity. When Catherine is attacked by their dog, the Lintons take her in, but send Heathcliff home. The Lintons visit, and Hindley and Edgar make fun of Heathcliff; a fight ensues. Heathcliff is then made to live in the manor's unheated, dusty attic and swears that he will one day have his revenge.
