Brighton and Hove (/ˈbraɪtən ... ˈhoʊv/ BRY-tən … HOHV) is a city and unitary authority area, ceremonially in East Sussex, England. There are multiple villages alongside the seaside resorts of Brighton and Hove in the district. It is administered by Brighton and Hove City Council, which is currently under Labour majority control.

The two resorts, along with Worthing and Littlehampton in West Sussex, make up the second most-populous built-up area of South East England, after South Hampshire. In 2014, Brighton and Hove City Council and other nearby councils formed the Greater Brighton City Region local enterprise partnership area.

In 1992, a government commission was set up to conduct a structural review of local government arrangements across England. In its draft proposals for East Sussex, the commission suggested two separate unitary authorities be created for the towns of Brighton and Hove, with the latter authority to include Hove, Worthing and the Adur District. Support within Brighton for its own unitary authority was high, however respondents in Hove expressed reservations towards a merger with Worthing and Adur. A report following consultation noted that more than 25% of respondents in both Brighton and Hove had "unprompted, indicated support for a merger of those two areas." Although this option had not been included in the draft proposals, subsequent polling indicated that the merger was the most popular option among residents.

Nevertheless, the proposal of a merger proved controversial, particularly in Hove. Hove Borough Council opposed the move on the grounds that Brighton would dominate affairs in the city, and the commission acknowledged that residents of Hove "have significant negative feelings towards Brighton" and greater identification towards Sussex. Ultimately, the view was taken that support for a single tier of government in both towns outweighed opposition to unification, and as a result the commission recommended that the borough councils of Brighton and Hove be made a single unitary authority independent of East Sussex County Council. In 1997, Brighton and Hove Borough Council was formed, and assumed responsibility for all matters of local government across both towns.

Twenty years earlier, as part of the Queen's Silver Jubilee celebrations, Brighton had been shortlisted as a candidate for city status, though eventually lost out to larger Derby. Following unification of the towns, Brighton and Hove applied for city status again as part of the Millennium City Status Competition, and was subsequently granted city status on 31 January 2001. As a result, the borough council became a city council.

Although the city now operates as a single entity, locals generally still consider Brighton and Hove to be separate settlements with different identities. Hove is largely residential and has its own distinct seafront and established town centre located around George Street, while Brighton has a higher profile as the country's most popular seaside resort, a significant digital economy, and hosts several festivals of national prominence. Recognition of the city's twin identities is evident from the continued popularity of the local saying "Hove, actually", a phrase which long predates unification.

Some organisations such as the local football club, Brighton and Hove Albion, and the bus company Brighton & Hove, predate the unification of the towns by several decades.

In 2014, Brighton and Hove formed the Greater Brighton City Region with neighbouring local authorities.
