The Troup-Harris Regional Library (THRL) is a public library system serving the counties of Troup, and Harris, Georgia, United States.

This program offers residents in supported libraries access to over 100 databases indexing thousands of periodicals and scholarly journals.

[4] The Troup-Harris Regional Library officially began in 2007 after neighboring Coweta County left the system in 2007 to begin their own.

[5] In December 2016 the library system opened their first new building for the city of Hoganville.

[6] This new library has over 11,200 square feet of space for book stacks, meeting areas, and computers, and replaced the old 3,000 square foot building which was too small to house the branch's entire collection.
