The Business Design Centre is a Grade II listed building located between Upper Street and Liverpool Road in the district of Islington in London, England. It was opened in 1862, originally named the Agricultural Hall and from 1884 the Royal Agricultural Hall, for holding agricultural shows. It was the home of the Royal Smithfield Club's Smithfield Show from 1862 to 1938. It hosted the Royal Tournament from its inauguration in 1880 until the event became too large for the venue and moved to Olympia in the early years of the 20th century. It hosted the first Crufts dog show in 1891.

Upper Street is the main street of the Islington district of inner north London, and carries the A1 road. It begins at the junction of the A1 and Liverpool Road, continuing on from Islington High Street which runs from the crossroads at Pentonville Road/City Road and runs roughly northwards from outside the main entrance to Angel Underground station, then past the Business Design Centre, then splits at Islington Green, then past The Screen On The Green cinema, past Islington Town Hall, ending at Highbury & Islington tube station on Highbury corner, where the A1 carries on as Holloway Road.
