Drogheda is an industrial and port town in County Louth on the east coast of Ireland, 56 km (35 mi) north of Dublin. Drogheda (including suburbs and environs) is the largest town in Ireland.

The River Boyne divided the town between County Meath and County Louth until the enactment of the Local Government (Ireland) Act 1898 which saw a large area of Drogheda south of the Boyne become part of an extended County Louth. With the passing of the County of Louth and Borough of Drogheda (Boundaries) Provisional Order, 1976, County Louth again grew larger at the expense of County Meath. The boundary was further altered in 1994 by the Local Government (Boundaries) (Town Elections) Regulations 1994. The 2007-2013 Meath County Development Plan recognises the Meath environs of Drogheda as a primary growth centre on a par with Navan.

In recent years Drogheda's economy has diversified from its traditional industries, with an increasing number of people employed in the retail, services and technology sectors. The town also has a community of independent artists and musicians who have been looking to the local economy rather than Dublin for employment.

With the expansion of the Irish economy in the 1990s, during the "Celtic Tiger" years, Drogheda became one of the main secondary locations for people who work in Dublin to buy a house, as property prices in the capital became prohibitive for many first-time home buyers. This was aided by the expansion of transport infrastructure in the direction of Drogheda i.e. the Swords and Balbriggan bypasses, the Boyne River Bridge and the increased number of commuter trains serving the town. Partly as a result, the downtown area of Drogheda has redeveloped, and two large shopping centres have opened, while several national and international retailers have opened stores. In 2007 the partial pedestrianisation of the town's main street, West Street, was completed.
