O’Reilly Auto Parts

O’Reilly Auto Parts is a major retailer specializing in automotive aftermarket parts, tools, and accessories for both professional mechanics and everyday drivers. The company was founded in 1957 in Springfield, Missouri, by the O’Reilly family, who opened their first store with a focus on reliable service and product availability. Over the years, O’Reilly has grown from a single location to a network of more than 6,400 stores as of October 2025, operating across the United States, Mexico, Canada, and Puerto Rico.

A significant milestone in O’Reilly’s history was its expansion beyond the Midwest, which accelerated through a combination of new store openings and targeted acquisitions. In the past five years, the company has continued to build on this strategy, entering new markets and strengthening its presence in North America. O’Reilly’s growth is supported by a robust distribution network, which ensures stores are well-stocked and able to serve both do-it-yourself customers and professional repair shops.

The brand’s dual focus on retail and commercial sales has allowed it to capture a broad customer base in a competitive industry. O’Reilly’s ongoing investment in new locations and infrastructure reflects a commitment to increasing market share and supporting long-term growth. Its established reputation, large-format stores, and consistent expansion make O’Reilly Auto Parts a reliable and visible presence in a variety of retail environments.
