Marathon Petroleum Corporation is a U.S.-based integrated downstream and midstream energy company headquartered in Findlay, Ohio. It operates one of the largest refining systems in the United States, converting crude oil and other feedstocks into gasoline, diesel, jet fuel, asphalt, petrochemicals, and renewable diesel for transportation, industrial, and commercial use. The company’s Refining & Marketing activities span key regions such as the Gulf Coast, Mid-Continent, and West Coast, supported by an extensive network of pipelines, terminals, barges, and logistics assets that move refined products efficiently to wholesale customers, independent retailers, and branded Marathon retail outlets nationwide.
Through its Midstream operations, largely held via its interest in MPLX LP, Marathon Petroleum provides gathering, processing, fractionation, storage, and transportation services for crude oil, refined products, natural gas, and natural gas liquids, underpinning the broader U.S. energy infrastructure. The addition of a Renewable Diesel segment further positions Marathon Petroleum in low-carbon fuel markets, making it a significant supplier of renewable diesel alongside its conventional petroleum products. Founded in 1887 and headquartered in Findlay, Ohio, the company today plays a central role in the U.S. fuel supply chain and energy logistics system.
