Bloomsbury is a ward in the London Borough of Camden, in the United Kingdom.

The ward has existed since the creation of the borough on 1 April 1965 and was first used in the 1964 elections, although its boundaries have evolved significantly over time.

The ward encompasses much of the historic area of Bloomsbury, including most of its well-preserved surviving Georgian development in the west.

This area is dense in land use and population, with a large proportion of institutional and commercial uses reflecting its Central London location.

The premises of University College London comprises a large part of this ward, along with its various student housing blocks, while the commercial centre of Tottenham Court Road runs down the centre from north to south.

The ward gained territory in the southeast from Holborn and Covent Garden around Bloomsbury Square.

The St Giles, Seven Dials and parts of Holborn/Covent Garden were removed from the ward in the south.

The ward extended east of Woburn Place/Russell Square to take in a residential area including the Brunswick Centre.
