The Tennessee Republican Party (TRP) is the affiliate of the United States Republican Party in Tennessee. It is often called the Tennessee Grand Old Party or the TN GOP.

Upon its entry into the Union in 1776 Tennessee was strongly Democratic-Republican. Tennessee became a two-party system for more than 20 years during the Jacksonian era. The Democratic Party was formed by Jackson followers and this party was dominant against the rival Republican Party created by John Quincy Adams. But in 1835, there was a turn in power of party and a Whig governor was elected. Tennessee after the Civil War was part of the Democratic South for about a century. East Tennessee however remained strongly Republican. Even though the state was predominantly Democratic two different presidential elections won the state of Tennessee in 1920 and 1928. In the 1960s and 1970s Republicans made a push into the Democratic power when in 1966, Howard Baker was elected US senator. Then again Republicans made another push, when Winfield Dunn was elected governor, the first Republican Governor in over 50 years.

Tennessee (ⁱ/tɛnɨˈsiː/) (Cherokee: ᏔᎾᏏ) is a U.S. state located in the Southeastern United States. Tennessee is the 36th most extensive and the 17th most populous of the 50 United States. Tennessee is bordered by Kentucky and Virginia to the north, North Carolina to the east, Georgia, Alabama, and Mississippi to the south, and Arkansas and Missouri to the west. The Appalachian Mountains dominate the eastern part of the state, and the Mississippi River forms the state's western border. Tennessee's capital and second largest city is Nashville, which has a population of 626,144.Memphis is the state's largest city, with a population of 670,902.

The state of Tennessee is rooted in the Watauga Association, a 1772 frontier pact generally regarded as the first constitutional government west of the Appalachians. What is now Tennessee was initially part of North Carolina, and later part of the Southwest Territory. Tennessee was admitted to the Union as the 16th state on June 1, 1796. Tennessee was the last state to leave the Union and join the Confederacy at the outbreak of the U.S. Civil War in 1861, and the first state to be readmitted to the Union at the end of the war.
