Who was the CEO of Walmart from 2014 to 2024?

Doug McMillon was Walmart’s CEO from 2014 to 2024.

McMillon became Walmart’s fifth chief executive on February 1, 2014, succeeding Mike Duke. His career was unusually connected to the retailer: he first worked for Walmart as a teenager, later became a buyer, and eventually led both Sam’s Club and Walmart International before reaching the top job.

As CEO, McMillon emphasized Walmart’s response to Amazon and other changing retail competitors. He increased investment in e-commerce, worked to improve the shopping experience across stores and digital channels, and supported higher wages, benefits, and training for many U.S. associates. He also promoted sustainability goals involving renewable energy, waste reduction, and packaging.

The date range can cause confusion because McMillon’s tenure extended beyond 2024; he remained CEO into January 2026 before retiring. That does not change the stored answer: Doug McMillon is the canonical person identified by the question. Mike Duke was his predecessor, while Sam Walton founded Walmart and was not the CEO during this period.
