The townland of Randalstown was originally known as An Dún Mór ("the great fort"), anglicised as Dunmore. This refers to a medieval motte-and-bailey castle built by the Irish on the west bank of the river Main just south of the town.[5] A castle known as Edenduffcarrick, later Shane's Castle, was built near Randalstown in the 14th century by the O'NeillsofClannaboy.
From at least the 1650s the town was known as "Iron Mills" (Muilinn Iarainn in Irish, anglicised "Mullynieren").[5] In 1667, the town was created a free borough and was officially renamed Randalstown.[5] It was renamed to mark the marriage of Randal MacDonnell, 1st Marquess of Antrim to Rose O'Neill of Shane's Castle.[5]
The 1798 United Irishmen rebellion began in Antrim following a meeting to prepare for revolt by the Ulster Directory on 1 February 1798, at McClean's Inn, Randalstown. Robert McClean's "Great Inn" had long been an Irish Volunteers meeting place. Following his death in 1790, his son Francis became the proprietor.[6]
Randalstown has a strong history of linen and iron industries. A memorial to this history is in the middle of the town and made from the original turbine used to generate mains electricity for the town and items salvaged from the Old Bleach Linen Company founded by James Webb in 1864. An old linen mill chimney from the Old Bleach factory can be seen from most parts of the town. The Dorma Old Bleach factory which operated from a neighbouring site closed down in 2002.
On 8 January 2010, PSNI Constable Peadar Heffron was seriously injured as a bomb exploded under his car on the Milltown Road near Randalstown. Dissident republicans were blamed for the attack.[7][8]
