Old Grand-Dad is a brand of bourbon whiskey distilled at the Jim Beam distillery in Clermont, Kentucky.

In 1899, Old Grand-Dad was sold to the Wathen family, whose broad interests in the whiskey business later formed the American Medicinal Spirits Company and the foundations of National Distillers Group.

During prohibition, the company produced "medicinal whiskey" for sick, blind, and lame patients.

Food critic Morgan Murphy said "The sweet corn of this whiskey is hot on the lips but has a mild finish of vanilla and baking spices.
