Arbroath or Aberbrothock /ɑrˈbroʊθ/ (Scottish Gaelic: Obar Bhrothaig, [opəɾˈvɾo.ɪkʲ]) is a former royal burgh and the largest town in the council area of Angus in Scotland, and has a population of 22,785. It lies on the North Sea coast, around 16 miles (25.7 km) ENE of Dundee and 45 miles (72.4 km) SSW of Aberdeen.

While there is evidence for settlement of the area now occupied by the town that dates back to the Iron Age, Arbroath's history as a town begins in the High Middle Ages with the founding of Arbroath Abbey in 1178. Arbroath grew considerably during the Industrial Revolution owing to the expansion of firstly the flax and secondly the jute industries and the engineering sector. A new harbour was built in 1839 and by the 20th century, Arbroath had become one of the larger fishing ports in Scotland.

The town is notable as the home of the Declaration of Arbroath, as well as the Arbroath Smokie.

The earliest recorded name for the town was 'Aberbrothock', a reference to the Brothock Burn which runs through the town, the prefix 'Aber' coming either from the Gaelic 'Obair', or the earlier term 'Aber' which could be either Goidelic or Brythonic for 'river mouth'. The name 'Aberbrothock' can be found in numerous spelling variations. In the earliest manuscripts available, it is seen as 'Abirbrothoke' (in the letter to Edward I confirming the Treaty of Salisbury, which agreed that the Queen regnant, Margaret, Maid of Norway would marry Edward I) and 'Aberbrothok' (in the subsequent letter giving consent for the marriage). In the Declaration of Arbroath, it is seen as 'Abirbrothoc'. Early maps show a number of variants including Aberbrothock, Aberbrothik, Aberbrothick, and Aberbrothwick.

Arbroath Abbey, in the Scottish town of Arbroath, was founded in 1178 by King William the Lion for a group of Tironensian Benedictine monks from Kelso Abbey. It was consecrated in 1197 with a dedication to the deceased Saint Thomas Becket, whom the king had met at the English court. It was William's only personal foundation — he was buried before the high altar of the church in 1214.

The last Abbot was Cardinal David Beaton, who in 1522 succeeded his uncle James to become Archbishop of St Andrews. The Abbey is cared for by Historic Scotland and is open to the public throughout the year (entrance charge). The distinctive red sandstone ruins stand at the top of the High Street in Arbroath.

King William gave the Abbey independence from its mother church and endowed it generously, including income from 24 parishes, land in every royal burgh and more. The Abbey's monks were allowed to run a market and build a harbour. King John of England gave the Abbey permission to buy and sell goods anywhere in England (except London) toll-free.
