William Grant & Sons Ltd. is an independent, family-owned Scottish company which distills Scotch whisky and other selected categories of spirits. It was established in 1887 by William Grant, and is now run by the descendants of the founder. It is the largest of the handful of Scotch whisky distillers remaining in family ownership. "William Grant & Sons" is often abbreviated to "W. Grant & Sons" or just "Grant's", after their leading blended whisky of the same name.

The company is the 3rd largest producer of Scotch whisky (10.4% market share) after Diageo (34.4%), and Pernod Ricard. The company's central headquarters are in Strathclyde Business Park, North Lanarkshire. Sales and marketing headquarters are in Richmond, London. The company is a member of the Scotch Whisky Association.

The master blender of Grant's is Brian Kinsman, who recently succeeded David Stewart who had been in his post for 47 years, the longest serving master blender with one distiller in the industry.
