Lionel, LLC is a designer and importer of toy trains and model railroads, based in Chesterfield Township, Michigan and currently in bankruptcy. Its roots lie in the 1969 purchase of the Lionel product line by cereal conglomerate General Mills.

Although Lionel, LLC now owns all of the trademarks and most of the product rights associated with Lionel Corporation, the original producer of Lionel trains founded in 1900, there is no direct connection between the two companies.
