2018 Miss Tennessee USA

The 2018 Miss Tennessee USA competition is the pageant that selects the representative for the state of Tennessee in the Miss USA pageant. Since 2001, the pageant has been held in the auditorium at Austin Peay State University in Clarksville, Tennessee.

Lynnette Cole, Miss Tennessee USA 2000, and Rachel Smith, Miss Tennessee USA 2007, are the only titleholders to win the Miss USA title. Five Miss Tennessee USA titleholders have formerly competed at Miss Tennessee Teen USA, and six have competed at Miss America. One of these is Allison Alderson, a "triple crown" winner who has held the Miss Tennessee Teen USA, Miss Tennessee, and Miss Tennessee USA titles, competing at all three major pageants.

Every year, each state holds a preliminary competition to choose their delegate for the Miss USA pageant. In some states (such as Texas and Florida), local pageants are also held to determine delegates for the state competition. The state winners hold the title "Miss State USA" for the year of their reign.

The most successful state is Texas, which has had the most semi-finalists and winners, including five consecutive Miss USA titleholders during the 1980s.[22] Other successful states include California, New York, Alabama, Tennessee and Georgia. The least successful states are Delaware, placing only once in 2015; Montana, which has not placed since the 1950s; South Dakota, which has only placed three times (the last time in 2016), and Wyoming, which gained only its second placement in 2010. The only state which has produced more than one Miss Universe is South Carolina.

The Miss Universe Organization licenses out the state pageants to pageant directors, who in some cases are responsible for more than one state. The most well established directorial groups are RPM Productions, created in 1980 (Alabama, Louisiana, North Carolina, South Carolina), and Vanbros, created in the early 1990s (Arkansas, Kansas, Missouri, Nebraska and Oklahoma). Future Productions direct the most states, seven, across the Midwest and Rockies.
