"Ridin'" (or Ridin' Dirty) is the second single from Chamillionaire's album, The Sound of Revenge, and features a guest rap by Krayzie Bone. Its title is often incorrectly assumed to be "Ridin' Dirty" due to the chorus. The lyrics concern racial profiling and police brutality, as well as the stereotyping of African Americans driving a vehicle with drugs or other contraband on the inside ("riding dirty"). The music video attempts to create a sense of the police abusing their powers for likely racist reasons, though the singer does admit to various crimes of that nature, including driving under the influence, juxtaposing police actions with wrestling scenes to show how the police allegedly treat suspects. The music video, filmed in Dallas, Texas, also has cameo appearances by Tom Lister Jr., Wish Bone, Layzie Bone, Play-N-Skillz, Chingo Bling, OG Ron C, Big Tuck, and Chamillionaire's younger brother Rasaq.

Ridin'was awarded "Best Rap Performance by a Duo or Group" at the 49th Annual Grammy Awards. It was also nominated for Best Rap Song. It became number one in December on the Piczo Chart 3 months after its physical release. The song also topped the Billboard Hot 100 in the U.S. for two weeks, and peaked at number 2 on the UK Singles Chart behind Shakira when it was released there.

The song ranked #3 on Rolling Stone's"100 Best Songs of 2006". It was the best selling ringtone in 2006, with 3.2 million sales, certified by the RIAA as the first multi-platinum Mastertone artist in history.

Number 91 on VH1's 100 Greatest Songs of Hip Hop. It was also awarded the last Best Rap Video at the MTV Video Music Awards, which was awarded in 2006.
