The Western Petroleum Marketers Association (WPMA) is a regional trade association for petroleum marketers, headquartered in Salt Lake City, Utah. WPMA is comprised of seven state petroleum marketing associations: Hawaii, Idaho, Montana, Nevada, New Mexico, Utah and Washington. Since 1953, WPMA has been assisting its member state associations in administering their programs, distributing legislative information, and providing convention and membership services.

WPMA hosts a National Convention and Convenience Store Expo in Las Vegas each year, which is well-attended by company owners and decision makers.

In 1990 WPMA started a Merit Scholarship program, and to date has awarded over 180 scholarships to the children of full-time employees of WPMA marketer member and associate member companies.
