Bray (Irish: Bré [bʲɾʲeː]) is a coastal town in north County Wicklow, Ireland. It is situated about 20 km (12 mi) south of Dublin city centre on the east coast, and parts of the town's northern outskirts are in County Dublin. It has a population of 33,512 making it the tenth largest urban area within Ireland (at the 2022 census). Bray is home to Ardmore Studios, and some light industry is located in the town, with some business and retail parks on its southern periphery. Commuter links between Bray and Dublin are provided by rail, Dublin Bus and the M11 and M50 motorways. The town is in a townland and civil parish of the same name.

Originally developed as a planned resort town in the 19th century, Bray's popularity as a seaside resort was serviced by the Dublin and Kingstown Railway, which was extended to Bray in 1854. During the late 20th century, the town's use as a resort declined when foreign travel became an option for holiday-makers. However, day-trippers continued to come to Bray during the summer months.

The name Bray is an anglicisation of the Irish Bré, whose meaning is unclear. Liam Price suggested it may be an old name for the River Dargle or a tributary. In 1875 P. W. Joyce mistakenly ascribed the Irish name Brí, an old word meaning "hill", referring in this case to Bray Head. In a 1905 Gaelic League publication advocating use of Irish-language postal addresses, Seosamh Laoide coined the name Brí Cualann "Brí in Cualu", as part of his policy that "If the name of the town [in Irish] be one word, the [ancient Gaelic] territory should be added to it in the genitive case". Brí and Brí C[h]ualann remained in use in the mid 20th century despite having been refuted by Liam Price and Osborn Bergin. Bré was adopted by statute in 1975.

During the medieval period of Irish history, Bray was situated on the southern border of the Pale, and the coastal district was governed directly by the English crown from Dublin Castle. Inland, the countryside was largely under the control of Gaelic Chieftains, such as the O'Toole and O'Byrne clans. Bray features on the 1598 map "A Modern Depiction of Ireland, One of the British Isles" by Abraham Ortelius as "Brey". William Brabazon, 1st Earl of Meath purchased the Killruddery Estate in Bray in 1627 with the establishment of the Earl title.

The Dublin and Kingstown Railway, the first in Ireland, opened in 1834 and was extended as far as Bray in 1854. With the coming of the railway in the mid-19th century, the town grew to become a seaside resort. It was developed primarily by local entrepreneurs as a planned resort town, modelled on the seaside resorts of the English south-coast, specifically Brighton. Hotels and residential terraces were built in the vicinity of the seafront. Railway entrepreneur William Dargan developed Victorian Turkish baths, designed by architect and sculptor Richard Barter in a Moorish style at a cost of £10,000. They opened in 1859 and were demolished in 1980, though the baths closed long before that.

Bray was a popular destination from the 1860s onwards. While small amenities such as regattas, firework displays and band performances were plentiful in the town, Bray failed to secure the necessary capital to develop major attractions and sustain tourism, leading to its decline in the early 1900s. Pleasure piers such as the Palace Pier were a mainstay of resorts at that time. Despite repeated efforts, Bray never acquired such a pier and abandoned plans to build one in 1906. Additional planned amenities which were never built included a concert hall, a theatre, an exhibition centre, a marine aquarium, winter gardens and an electrified tramway along the seafront. It experienced a brief revival from British tourists in the years immediately after World War II. However, Bray's popularity as a seaside resort declined significantly when foreign travel became an option for holiday-makers. Its proximity to Dublin still makes it a popular destination for day-trippers from the capital.

The town is situated on the east coast to the south of County Dublin. Shankill, County Dublin lies to the north, and Greystones, County Wicklow to the south. The village of Enniskerry lies to the west of the town, at the foot of the Wicklow Mountains. People participate in such sports as sailing, rowing, and swimming. The beach and seafront promenade are used by residents and visitors. While Bray's promenade and south beach is to a Blue Flag standard, the north beach has been affected by erosion and the leaching of a variety of toxic chemicals – including asbestos, rusted metal, plastics, and bricks – into the groundwater since the closure and sale of the former Bray Urban Council municipal landfill, immediately beside the beach, containing 200,000 tonnes or 104,000 cubic metres of waste. The dump was closed in 1968 and sold to Woodbrook golf club in 1992. By 2017, plans were being discussed to deal with the situation.

The River Dargle which enters the sea at the north end of Bray rises from a source near Djouce, in the Wicklow Mountains. Bray Head is situated at the southern end of the Victorian Promenade with paths leading to the summit and along the sea cliffs. The rocks of Bray Head are a mixture of greywackes and quartzite. There is a large cross at the summit.
