Abbey River, Limerick in the context of "The Custom House, Limerick"

Limerick (/ˈlɪmərɪk/ LIM-ər-ik; Irish: Luimneach [ˈl̪ˠɪmʲ(ə)nʲəx]) is a city in western Ireland, in County Limerick. It is in the province of Munster and is in the Mid-West which comprises part of the Southern Region. With a population of 102,287 at the 2022 census, Limerick is the third-most populous urban area in Ireland, and the fourth-most populous city on the island of Ireland. It was founded by Scandinavian settlers in 812, during the Viking Age.

The city straddles the River Shannon, with the historic core of the city located on King's Island, which is bounded by the Shannon and Abbey Rivers. Limerick is at the head of the Shannon Estuary, where the river widens before it flows into the Atlantic Ocean. Limerick City and County Council is the local authority for the city.

King's Island (Irish: Oileán an Rí) is an area of central Limerick, Ireland. The area is often referred to colloquially as The Island and consists of two distinct areas, Englishtown and St Mary's Park. The historical city of Limerick known as Englishtown is located on the southern end and St Mary's Park; a local authority housing estate is located on the northern end.

The island is formed from a distributary of the River Shannon. The Abbey River diverts from the Shannon before meeting it again at a confluence near the Potato Market.
