Samuel Leonard Crocker (March 31, 1804 – February 10, 1883) was a businessman and U.S. Representative from Taunton, Massachusetts.

Later known as Crocker and Richmond, the firm was involved in several manufacturing businesses of Taunton during the early 19th century.

Located along the Wading River in Norton, Massachusetts, the company was incorporated in 1831 with a working capital of $200,000 (~$6.74 million in 2023).

Established at the site of Horatio Leonard & Company, which was originally built in 1823, the Old Colony Iron Works became the largest producer of nails in New England by the mid-1870s.

In his later life, Crocker was a member of the Old Colony Historical Society,[7] and a trustee of the Taunton Lunatic Hospital.
