The Lehigh Coal & Navigation Company, also known in the Lehigh Valley as the Old Company, was a mining and transportation company which grew out of the Lehigh Coal Mine Company. It was created from the merger of the Lehigh Coal Company and the Lehigh Navigation Company.

The Lehigh Coal Mining Company was a coal mining and transportation company that operated in Pennsylvania and the surrounding states from 1822 to 1976. Founded by industrialist Asa Packer, the company was one of the first in the United States to use steam-powered locomotives to transport coal from the mines to market. The company was responsible for creating the Lehigh Valley Railroad, which was the first railroad to be constructed in the United States.

The Lehigh Coal Mining Company was formed in 1822 by Asa Packer, who had previously worked in the coal industry in Pennsylvania. Packer saw an opportunity to make a profit by buying up land and coal deposits in the region. He also believed that the use of steam-powered locomotives could make the transportation of coal more efficient and less expensive. As a result, the company was one of the first to use locomotives to transport coal from the mines to the markets.

The Lehigh Coal Mining Company was successful in its early years, and by the late 1800s it had become one of the largest coal mining companies in the United States. The company operated mines in Pennsylvania, New Jersey, and New York, and it also had its own fleet of locomotives and coal cars. The company also owned the Lehigh Valley Railroad, which was the first railroad to be constructed in the United States.

The Lehigh Coal Mining Company continued to be successful until the mid-1900s, when the increasing use of oil and natural gas began to reduce demand for coal. As a result, the company began to struggle and eventually went out of business in 1976. Despite its eventual demise, the Lehigh Coal Mining Company had a lasting impact on the coal industry in the United States. It was one of the first companies to use steam-powered locomotives to transport coal, and it also helped create the Lehigh Valley Railroad, which was the first railroad to be constructed in the United States.
