National Meat Association (NMA) is a non-profit, industry trade association headquartered in Oakland, California. NMA was formed by the merger of Pacific Coast Meat Association, itself formed in 1948, and Western States Meat Packers Association which had launched in 1946 in San Francisco, California. NMA was once known as Western States Meat Association, but has since grown to national prominence with approximately 500 member companies. The association provides expert guidance and regulatory assistance to meat packers and processors. It has a biennial trade show called MEATXPO.
