Lufkin was founded in 1884 and named for Abraham P. Lufkin. It originally served as a stop on the Houston, East and West Texas Railway. It was officially incorporated on October 15, 1890. Lufkin continued to serve as a stop on the railroad until 1890. Three businessmen founded Angelina Lumber Company, which led to much of the economic prosperity Lufkin later enjoyed. When the so-called "timber boom" came to an end, a new "golden era of expansion" began. Lufkin became more industrialized with the opening of Lufkin Industries and Southland Paper Mill. In the mid-1960s, a cultural expansion began, and improvements were made to education and the way of life, including museums and the opening of a new library.

The City of Lufkin has a council–manager government, with six city council members, a mayor, and a city manager. The Lufkin Independent School District encompasses most of Lufkin and operates almost all of the schools within Lufkin. Additionally, Angelina College, a community college, is located in Lufkin.
