Marc Predka (born April 21, 1975) better known by his stage name Tha Trademarc, is an American hip hop artist. He first came to prominence when he and his first cousin, WWE wrestler John Cena, collaborated on the 2005 album You Can't See Me, including Cena's entrance theme "My Time Is Now". He also appeared in the music videos of the songs, "Bad Bad Man" and "Right Now" with John Cena respectively. Prior to the album, Trademarc appeared on Cena's first WWE DVD Word Life. He now works as a classroom specialist for the Peace Corps of America.

In August 2007, Trademarc appeared at Total Nonstop Action Wrestling's (TNA) Hard Justice pay-per-view as the "new boyfriend" of Karen Angle, later revealed to be a ruse when Karen and Trademarc helped Karen's "estranged" husband Kurt Angle win the match. He appeared again on iMPACT! the next week. While working with TNA he also re-recorded Kurt Angle's entrance music, mixing in a rap he did over a Lunatic Fringe beat with the TNA-composed "My Quest" to form the hip hop theme "Gold Medal". In 2008, he released his first solo debut album Inferiority Complex. He recently worked with independent artist T-Nova on a few tracks that have yet to be released.
