Kellogg’s Headquarters Address, Corporate Office Location, and Contact Details

About

The Kellogg Company — doing business as Kellogg’s — was an American multinational food manufacturing company headquartered at 1 Kellogg Square, Battle Creek, Michigan 49017 for over 117 years, founded in 1906 by Will Keith (W.K.) Kellogg in Battle Creek, Michigan. On October 2, 2023, Kellogg Company finalized the separation of its businesses into two fully independent, publicly traded companies: WK Kellogg Co (NYSE: KLG), retaining the North American cereal business and the Battle Creek headquarters at 1 Kellogg Square; and Kellanova, housing the global snacking, international cereal, and plant-based food businesses with headquarters relocated to Chicago, Illinois.

WK Kellogg Co — the cereal spinoff — operates iconic cereal brands including Corn Flakes, Frosted Flakes, Froot Loops, Special K, Rice Krispies, Raisin Bran, and Eggo waffles, and remains rooted in Battle Creek — the city W.K. Kellogg put on the map as the “Cereal Capital of the World.” Kellanova — the snacking/global business — operates brands including Pringles, Pop-Tarts, Cheez-It, MorningStar Farms, and international Kellogg’s cereals; it was subsequently acquired by Mars, Inc. in a landmark $35.9 billion transaction completed in March 2024 — one of the largest food industry acquisitions in history — making Kellanova a Mars subsidiary no longer independently traded.

About 1 Kellogg Square and Battle Creek’s Cereal Capital legacy: The 1 Kellogg Square campus in downtown Battle Creek has been the Kellogg Company’s corporate nerve center since the company’s modern era — a landmark address in a city whose identity is inseparable from W.K. Kellogg’s 1906 invention of corn flakes and the subsequent boom that made Battle Creek the global headquarters of the ready-to-eat cereal industry. WK Kellogg Co’s retention of 1 Kellogg Square following the October 2023 split preserves Battle Creek’s status as the official home of the Kellogg’s cereal legacy — while Kellanova’s relocation to Chicago and subsequent Mars acquisition signals the full globalization of the snacking portfolio that Kellogg’s had built over more than a century. The W.K. Kellogg Foundation — one of the largest private foundations in the United States, with over $9 billion in assets — also remains headquartered in Battle Creek, continuing W.K. Kellogg’s philanthropic mission of supporting children and families.
