The Angel, Islington, is a historic landmark and a series of buildings that have stood on the corner of Islington High Street and Pentonville Road in Islington, London, England. The land originally belonged to the Clerkenwell Priory and has had various properties built on it since the 16th century. An inn on the site was called the Angel Inn by 1614, and the crossing became generally known as the Angel. The site was bisected by the New Road, which opened in 1756, and properties on the site were rebuilt several times up to the 20th century. The corner site gave its name to Angel tube station, opened in 1901, and the surrounding Angel area of London.

The current structure was completed in 1903 and was known as the Angel Hotel. The building was acquired by J. Lyons and Co. in 1921 and was used as a restaurant. In 1935 it was chosen as a property for the British version of Monopoly. The building was sold to the London County Council in 1959 to be demolished as part of plans for road improvement works that did not take place. It was returned to private ownership, renovated from 1979 and reopened in 1982 as the Angel Corner House. It contained a branch of the Co-operative Bank until 2024. It is currently used as offices, and is a grade II listed building.

In the early 16th century a building in this area of London on the Great North Road was known as the Sheepcote. It was named after lands belonging to St John's Priory. The building was being used as an inn by the end of the 16th century and was known as the Angel by 1614. The inn took its name from the Angel of the Annunciation which appeared on the sign.

The Angel Inn became a useful stop when travelling from the City of London, as the rural area outside it was considered dangerous, with travellers having armed escorts from Wood's Close to Islington. Despite its name, and common association with Islington, the grounds of the inn and all of the western edge of Islington High Street were in neighbouring Clerkenwell.

By 1630, the inn was owned by William Riplingham, officer of the Great Wardrobe. Riplingham built an extension of the courtyard ranges on the site of the Angel Inn around 1638, for which he was fined due to breaking building regulations. These ranges survived up to the early 19th century. By 1677, the Angel was owned by James Compton, 3rd Earl of Northampton, and occupied by Edward Fawcett, who ran the inn until his death in 1696. The premises accommodated livestock traders (drovers) destined for Smithfield Market, as well as long-distance travellers.

In the early 18th century, the Angel was the largest coaching house in a row of several along Islington High Street. Robert Bartholomew took over ownership of the inn in 1744 and was succeeded by his son, Christopher, around 1766, who continued to run it until the end of the century. The inn was the subject of William Hogarth's 1747 drawing, The Stage-Coach, Or The Country Inn Yard, which depicted busy coaching inn trade and traffic. In his book The Inns and Taverns of Old London published in 1909, Henry C. Shelley said "The Angel dates back to before 1665... In the seventeenth century and later, as old pictures testify, the inn presented the usual features of a large old country hostelry."

The building of the New Road in 1756 bisected the Angel Inn site and the stable buildings were cut off on the southern side. The inn was on the northern side, on the corner of what is now the junction of Islington High Street and Pentonville Road, while the stables were now on what is St John Street, adjacent to the New Inn, which had been established in 1744. The Angel benefited from the extra traffic brought by the New Road, and in addition to accommodation provided a number of assembly rooms for public meetings. The author and political activist Thomas Paine is believed to have begun writing Rights of Man at the Angel in 1790, and there is a monument on Islington High Street commemorating this.

By the start of the 19th century, fields south of the Angel were being built on, resulting in all land towards the City of London becoming urban. The Angel was rebuilt during 1819 and 1820 to become a post house and meeting place for various London businesses. The redevelopment was directed by Charles Smith, and subsequently let to James Smith. The size of the inn was reduced and adjacent plots were sold off, allowing development of houses and shops, though the inn's grounds remained substantial. It was now advertised as the "Angel Inn Tavern and Hotel for Gentlemen and Families", and the front of the tavern faced the New Road.
