GlenAllachie is a Scottish whisky distillery located in the Speyside region of Scotland. It was founded in 1967 by William Delmé-Evans, who was also responsible for designing and building the distillery.

GlenAllachie was initially used as a blending whisky for the Mackinlay McPherson and White Horse blends, but it was eventually purchased by Pernod Ricard in 1989 and became part of the Chivas Brothers portfolio.

In 2017, GlenAllachie was sold to a group of investors led by Billy Walker, a veteran of the whisky industry who had previously worked at other distilleries such as BenRiach and GlenDronach. Under his leadership, GlenAllachie has undergone a significant transformation, with the release of new expressions and the expansion of its production facilities.

GlenAllachie produces a range of single malt whiskies, including 10-year-old, 12-year-old, and 15-year-old expressions, as well as cask strength and limited edition bottlings. The whisky is known for its fruity and floral notes, as well as its smooth and balanced flavour profile.
