The Old Bushmills Distillery is a distillery in Bushmills, County Antrim, Northern Ireland. As of December 2014, it was in the process of transitioning from ownership by Diageo plc to Jose Cuervo. All of the whiskey bottled under the Bushmills whiskey brand is produced at the Bushmills Distillery and uses water drawn from Saint Columb's Rill, which is a tributary of the River Bush. The distillery is a popular tourist attraction, with around 120,000 visitors per year.

The company that originally built the distillery was formed in 1784, although the date 1608 is printed on the label of the brand – referring to an earlier date when a royal licence was granted to a local landowner to distil whiskey in the area. After various periods of closure in its subsequent history, the distillery has been in continuous operation since it was rebuilt after a fire in 1885.
