Meijer Inc. (, ; stylized as meijer) is an American supercenter chain that primarily operates throughout the Midwestern United States. Its corporate headquarters are in Walker, Michigan, which is a part of the Grand Rapids metropolitan area.

About half of the company's 253 stores are located in Michigan; the others are in Illinois, Indiana, Kentucky, Ohio, and Wisconsin. The chain is ranked by Forbes as the 13th-largest private company in the United States, and is the country's 21st-largest retailer by revenue as of 2020. History Meijer was founded as Meijer's in Greenville, Michigan, in 1934 by Hendrik Meijer, a Dutch immigrant. Meijer was a local barber who entered the grocery business during the Great Depression. His first employees included his 14-year-old son, Frederik Meijer, who later became chairman of the company. The current co-chairmen, brothers Hank and Doug Meijer, are Hendrik's grandsons. After studying trends in the grocery industry, Meijer was among the first stores to offer self-service shopping and shopping carts. He also offered staple items, such as vinegar, at bargain prices. The Greenville store was successful and additional Meijer groceries were opened in Cedar Springs (1942) and Ionia (1946). The first Grand Rapids store opened on South Division Avenue in 1949. By the 1960s, the company had over two dozen stores located throughout West Michigan. In 1962 Meijer launched its modern format with a store at the corner of 28th Street and Kalamazoo Avenue in Grand Rapids.

The store was built with thick floors, so should the concept fail, the nongrocery half could be converted into an indoor car dealership. New stores were built in the same manner until the mid-1970s, when an architect mentioned the extra cost to management. This was followed by the first Mid-Michigan location in Delta Charter Township, Michigan, in 1966 and the first Metro Detroit store in Ypsilanti, Michigan, in 1972. Meijer expanded into Northern Michigan with their 33rd location in Traverse City opening in 1977. Fred Meijer took over the company upon his father's death in 1964. Under his leadership, the Thrifty Acres stores became a success and were renamed Meijer in 1986. Meijer's stand-alone grocery operations continued until the early 1990s, as the larger stores
