Ayrshire (Scottish Gaelic: Siorrachd Inbhir Àir, pronounced [ˈʃirˠəxk iɲiˈɾʲaːɾʲ]) is a historic county and registration county in south-west Scotland, located on the shores of the Firth of Clyde. Its principal towns include Ayr, Kilmarnock and Irvine and it borders the counties of Renfrewshire and Lanarkshire to the north-east, Dumfriesshire to the south-east, and Kirkcudbrightshire and Wigtownshire to the south. Like many other counties of Scotland it currently has no administrative function, instead being sub-divided into the council areas of North Ayrshire, South Ayrshire and East Ayrshire. It has a population of approximately 366,800.

The electoral and valuation area named Ayrshire covers the three council areas of South Ayrshire, East Ayrshire and North Ayrshire, therefore including the Isle of Arran, Great Cumbrae and Little Cumbrae. These three islands are part of the County of Bute and are sometimes included when the term Ayrshire is applied to the region. The same area is known as Ayrshire and Arran in other contexts.


Ayrshire is roughly crescent-shaped and is a predominantly flat county with areas of low hills; it forms part of the Southern Uplands geographic region of Scotland. The north of the county contains the main towns and bulk of the population. East of Largs can be found the Renfrewshire Heights, which continue south to the hill-country around Blae Loch.

Southern Ayrshire shares with the Galloway counties some rugged hill country known as the Galloway Hills. These hills lie to the west of the A713 (Ayr to Castle Douglas road) and they run south from the Loch Doon area almost to the Solway Firth. To the east of this route through the hills lie the Carsphairn and Scaur Hills which lie to the south east of Dalmellington and south of New Cumnock. Glen Afton runs deep into these hills.

Ayrshire is one of the most agriculturally fertile regions of Scotland. Potatoes are grown in fields near the coast, using seaweed-based fertiliser, and in addition the region produces pork products, other root vegetables, and cattle (see below);[citation needed] and summer berries such as strawberries are grown abundantly.

A number of small islands in the Firth of Clyde are part of Ayrshire, the chief of these being Horse Isle, Lady Isle and Ailsa Craig.


The main rivers flowing to the Clyde coast are, from north to south, the following:
