About Jacqueline Mars

Jacqueline Mars is a co-owner of Mars, Incorporated, one of the largest privately held companies in the world. The Mars family business, founded by her grandfather Frank Mars in 1911, produces some of the most recognized consumer brands on the planet, including M&M's, Snickers, Milky Way, Skittles, Twix, Pedigree, Whiskas, and Uncle Ben's. Jacqueline, along with her brother John, inherited the company from their father Forrest Mars Sr., who built it into a global powerhouse.

Jacqueline served on the Mars board of directors for decades, providing steady governance and strategic insight that helped the company navigate generational transitions while maintaining its commitment to quality and the famous 'Five Principles' — Quality, Responsibility, Mutuality, Efficiency, and Freedom. Under the family's stewardship, Mars has grown into a company generating over $50 billion in annual revenue across confectionery, pet care, food, and veterinary health.

Beyond her role at Mars, Jacqueline is a dedicated equestrian and philanthropist. She has been deeply involved in supporting the arts, land conservation, and community causes throughout her life. Her commitment to keeping Mars private and family-controlled has allowed the company to invest for the long term, maintain its distinctive culture, and uphold the values that have made it a beloved institution for over a century.
