The National Lubricating Grease Institute is an international trade association that serves the grease and gear lubricant industry. It exists to promote research and development of lubrication technology. It also publishes industry standards for greases.

The NLGI was incorporated by a small number of companies in 1933 to create a code for the National Recovery Act. The original name of the organization was the National Association of Lubricating Grease Manufacturers, Inc. The name was changed in 1937 as the industry recognized the need for a joint development and standards association and membership grew.

According to information posted by the NLGI in 2004, the institute has member organizations in 26 countries, while subscriptions to its journal, the NLGI Spokesman, represent 50 countries.

The NLGI is a not-for-profit corporation whose membership includes grease manufacturers and sales organizations, associated equipment manufacturers, industry suppliers, service organizations, research and educational groups. Membership is by company, not individual.
