Monkey Shoulder is a brand of Scotch whisky produced by William Grant & Sons in Scotland.

[1] As of 2023, Monkey Shoulder is the world's third best-selling brand of Scotch whisky, trailing Johnnie Walker and The Macallan.

[2] Monkey Shoulder was introduced in 2003 as a brand of blended malt whisky (formerly called "vatted malt whisky") primarily for mixing, occupying a middle ground between blended Scotch (which can contain grain whisky) and single malt whisky (which cannot).

[3] Originally a blend from the Balvenie, Glenfiddich, and Kininvie distilleries, its current composition is not publicly known, although its constituent malt whiskies originate from the Speyside region.

[4] The name refers to a repetitive strain injury that distillery workers once commonly were afflicted with after long shifts of turning malt by hand.
