Brighton Museum & Art Gallery is a municipally-owned public museum and art gallery in the city of Brighton and Hove in the South East of England. It is part of Brighton & Hove Museums. It costs £9.50 for a yearly pass, discounted to £7 for Brighton and Hove residents and students at local universities.

The building which houses the collection is part of the Royal Pavilion Estate and was originally built for the Prince of Wales, later George IV and completed in 1805. It was initially intended as a tennis court but had never been finished, and later served as cavalry barracks.

After the death of George IV in 1830, his successor King William IV also stayed in the Pavilion on his visits to Brighton. However, after Queen Victoria's last visit to Brighton in 1845, the Government planned to sell the building and grounds. The Brighton Commissioners and the Brighton Vestry successfully petitioned the government to sell the Pavilion to the town for £53,000 in 1850 under the Brighton Improvement (Purchase of the Royal Pavilion and Grounds) Act 1850.

In September 1851 it was announced that part of the Pavilion was to be appropriated for annual art exhibitions and two months later the first of these was held. The local talent to which it was confined included Frederick Nash and Copley Fielding. The room devoted to the exhibition was the original South Gallery, now the First Conference Room, but later the exhibitions even spread to the Great Kitchen.

The stable building of the Pavilion estate, adjacent to the current museum premises, was used as a museum as early as 1856. It is now the site of the Brighton Dome – a performing arts venue.

The museum and art gallery occupied its current situation in the building in 1902. A major refurbishment of the museum and art gallery costing £10 million occurred in 2002. As a result, the traditional entrance to the museum and art gallery became the entrance of the Dome, the latter taking the museum's former entrance.

• A pair of breeches worn by George IV. The breeches are part of the royal wear section in the Costume & Textiles collection. They were made in 1827 and are hand stitched in green wool fabric. Breeches were worn in the 18th and early 19th century, but by 1810 trousers were becoming more popular. George IV preferred to wear breeches and banned trousers from court until 1815.
• A Kinemacolor camera made by Moy & Bastie around 1910. Kinemacolor was developed by George Albert Smith (one of the early pioneers in British film-making in Brighton & Hove) and was the first commercially viable colour film technique. The camera is part of the film and media collection.
• A hand-enamelled wall plaque made in 1934–1939 depicting life in Imperial India. It was designed by Clarice Cliff using a scene taken from the British Empire Panels designed by Frank Brangwyn. Cliff adapted designs from three of Brangwyn's panels which were produced by Royal Staffordshire Pottery.
• A toy toolbox containing miniature tools including a mallet, corkscrew and a screwdriver in the toy collection based at Hove Museum & Art Gallery. The handwritten ink on the toolbox lid reads ‘1846 Toolbox ELD from CLD’. It was made by Charles Lutwidge Dodgson, better known as author, photographer and mathematician Lewis Carroll.
• A portrait painted in coloured beeswax found fixed over the face of a mummified body in the Roman cemetery at Hawara in Egypt from the 2nd Century. His white robes are a deliberate display of status, distinguishing him as a member of the elite class of Romans who had settled in Egypt.
• Vietnamese water puppets from the mid-20th Century, hand painted and carved out of wood. Today, schools in Vietnam teach this art, once a guarded secret and passed down only from father to son. Water provides the magic and hides the mechanism of the puppet. Teu is the master of ceremonies and he introduces many different characters who perform their own story in turn.
• Edward Thomas Booth's hunting outfit, including leather wading boots, hat and gun. Booth's large collection of British Birds was developed into a museum in 1874. At this point it was known as Booth Museum of British Birds and was not open to the public, which occurred gradually with charitable fundraising events. By then he had formulated his ambition to exhibit one example of every species British bird and set about the task building up his collection and travelled around the country to collect his specimens.
• A drinking beaker from the local history collection made from horn, dating from the early 19th century. Around this time Brighton had one inn for every thirty houses. The beaker has the faint inscription: ‘Greyhound Inn Brighton, 1821'. The Greyhound Inn was situated at the corner of Pool Valley in Brighton.
• The Hove amber cup, which is considered to be one of Britain's most important Bronze Age finds. It was discovered in 1856 when a burial mound was excavated to make way for the building of Palmeira Avenue, Hove. Inside the mound was an oak coffin which contained bone fragments, a dagger, a whetstone and an axe head as well as the Amber Cup, made from a single piece of amber.
