Frazier Othel Thompson III (born July 3, 1980), known professionally as Trae tha Truth (shortened to Trae), is an American rapper. He first gained recognition with his guest appearance on fellow Houston rapper Z-Ro's album, Look What You Did to Me (1998). After two self-released albums, he further established himself with his third album and major label debut, Restless (2006), which entered the Billboard 200, along with his collaborative album as part of the duo Assholes by Nature (ABN), It Is What It Is (2008).

Thompson has released 11 solo studio albums, as well as 26 mixtapes and two projects as part of ABN, with Z-Ro. He is also known for his "I'm On" series of singles, which have featured several prominent rappers since its first installment in 2011. He signed with fellow Southern rapper T.I.'s Grand Hustle Records in 2012, and was named the label's vice president (VP) in 2017.

Trae tha Truth gained exposure on the Houston rap scene in 1998, when he made his rapping debut with a guest appearance on Z-Ro's album Look What You Did to Me. In 2003, he began his solo career with the album Losing Composure. 2004's Same Thing Different Day, 2006's Restless, and 2007's Life Goes On followed shortly after. Trae Tha Truth has also worked relentlessly with fellow Houston rapper Chamillionaire on his various Mixtape Messiah series.

He also collaborated with Z-Ro to form the duo ABN, or Assholes by Nature. They have released two albums, Assholes by Nature (2003) and It Is What It Is (2008).

In 2008, Trae Tha Truth was awarded by the mayor of Houston, Bill White, and Council Member Peter Brown with his own day, Trae Day, in honor of his outstanding work within the community. This is the first time the honor has been extended to a rap artist. Trae Day is celebrated every year on July 22.

Trae Tha Truth was involved in a fight with Texas rapper Mike Jones at the 2008 Ozone Awards. It was recently suspected that Trae Tha Truth's music was banned from Houston's local radio Station, 97.9 The Boxx.

Trae Tha Truth hosted the second annual Trae Day in July 22, 2009, near Texas Southern University. After the event had ended, eight people, ranging in age from 14 to 21, were shot near a parking garage located on the Texas Southern University campus. One of several people charged with shooting into the crowd was Sauce Walka. When he explained to the morning crew at radio station KBXX "97.9 The Box" that he did not condone the shooting, he was accused by one of the personalities of being responsible for the violence per the lyrical content. When Trae Tha Truth retaliated against her on a mixtape, KBXX banned Trae Tha Truth's music and contributed music from the station and ordered their personalities not to play his music. It caused backlash in the music community, as several DJs at KBXX were terminated from their positions due to playing songs that featured Trae. Due to his inability and hindrance from being able to promote his music in Houston as a result, Trae filed a lawsuit against KBXX early in 2010, citing damages to his career.

After creating a buzz for himself, T.I. announced that he had signed Trae Tha Truth to Grand Hustle Records on March 1, 2012. On October 9, 2012, Trae was featured on the annual BET Hip Hop Awards cypher, alongside his Grand Hustle label-mates Iggy Azalea, B.o.B, Chip, and T.I. His first Grand Hustle album, then-titled Banned, was scheduled to be released in 2014. However, prior to that, he was involved in the recording process for the Grand Hustle Records compilation album. His Grand Hustle Records debut titled Tha Truth was released on July 24, 2015.
