The Missouri Lumber and Mining Company (MLM) was a large timber corporation with headquarters and primary operations in southeast Missouri. The company was formed by Pennsylvania lumbermen who were eager to exploit the untapped timber resources of the Missouri Ozarks to supply lumber, primarily used in construction, to meet the demand of U.S. westward expansion. Its primary operations were centered in Grandin, a company town it built starting c. 1888. The lumber mill there grew to be the largest in the country at the turn of the century and Grandin's population peaked around 2,500 to 3,000. As the timber resources were exhausted, the company had to abandon Grandin around 1910. It continued timber harvesting in other parts of Missouri for another decade. While some of the buildings in Grandin were relocated, many of the remaining buildings were listed on the National Register of Historic Places in 1980 as part of the state's historic preservation plan which considered the MLM a significant technological and economic contributor to Missouri.

Grandin is a city in Carter County, Missouri, United States. The population was 226 at the 2020 census.
