Glen Flagler is a distillery built in 1965 in the Moffat complex by Inver House Distillers. It was only operational for some 20 years, when it was primarily used as a component in Inver House's blends Mac Arthur's and Pinwinne, although it was also bottled as a single malt in the 70s and 80s.

A Glen Flagler from the early 1970s imported to Italy by Ferraretto, Milan. Glen Flagler was primarily used for the blends of the Inver House group—Inver House, MacArthur’’s and Pinwinnie—which the Moffat complex belonged to, but the distillery also released bottlings of its single malt in the 1970s and 1980s in a 5 year old, an 8 year old and a 12 year old.
