Keats House is a museum in a house once occupied by the Romantic poet John Keats. It is in Keats Grove, Hampstead, north London. Maps prior to ca.1915 show the road with one of its earlier names, John Street; the road has also been known as Albion Grove. The building was originally a pair of semi-detached houses known as "Wentworth Place". John Keats lodged in one of them with his friend Charles Brown from December 1818 to September 1820. These were perhaps Keats's most productive years. According to Brown, "Ode to a Nightingale" was written under a plum tree in the garden.

While living in the house, Keats fell in love with and became engaged to Fanny Brawne, who lived with her family in the adjacent house. Keats became increasingly ill with tuberculosis and was advised to move to a warmer climate. He left London in 1820 and died, unmarried, in Italy the following year.

The house is a Grade I listed building.

The house was built during 1814–1815 and was probably completed between November 1815 and February 1816. The house was one of the first to be built in the area known as the Lower Heath Quarter.

John Keats ( /ˈkiːts/; 31 October 1795 – 23 February 1821) was an English Romantic poet. He was one of the main figures of the second generation of romantic poets along with Lord Byron and Percy Bysshe Shelley, despite his work only having been in publication for four years before his death.

Although his poems were not generally well received by critics during his life, his reputation grew after his death, so that by the end of the 19th century he had become one of the most beloved of all English poets. He had a significant influence on a diverse range of later poets and writers. Jorge Luis Borges stated that his first encounter with Keats was the most significant literary experience of his life.

The poetry of Keats is characterized by sensual imagery, most notably in the series of odes. Today his poems and letters are some of the most popular and most analyzed in English literature.

John Keats was born on 31 October 1795 to Thomas and Frances Jennings Keats. Keats and his family seemed to have marked his birthday on 29 October, however baptism records give the birth date as the 31st. He was the eldest of four surviving children; George (1797–1841), Thomas (1799–1818) and Frances Mary "Fanny" (1803–1889). Another son was lost in infancy. John was born in central London although there is no clear evidence of the exact location. His father first worked as a hostler at the stables attached to the Swan and Hoop inn, an establishment he later managed and where the growing family lived for some years. Keats believed that he was born at the inn, a birthplace of humble origins, but there is no evidence to support this. The Keats at the Globe pub now occupies the site, a few yards from modern day Moorgate station. He was baptised at St Botolph-without-Bishopsgate and sent to a local dame school as a child.
