"Grillz" is a song by American rapper Nelly from his compilation album Sweatsuit. The song features Paul Wall and Ali & Gipp. Brandi Williams also does back-up vocals on the song, but is not officially credited as a featured artist (but does appear in the video). The song was produced by Jermaine Dupri. The song is about grills, the cosmetic dental apparatuses. It samples the 2004 hit "Soldier" by Destiny's Child. Rappers Big Boi and Iamsu! makes a cameo appearance in the music video.

There is a remix, featuring Chingo Bling. Another official remix is a West Coast remix which features Diamonique and Lil Rob.

Fabolous interpolated lines from the chorus in the beginning of his song "The Wake" off of There is no Competition 2: the Grieving Music EP

In six weeks, "Grillz" reached the top five of the Billboard Hot 100, and number one in its tenth week (in 2006), becoming Nelly's fourth number one hit. It also became #1 on the Hot Ringtones chart. In the UK, it became his least successful single since "Iz U" charting at only #24. "Grillz" samples "Soldier" by Destiny's Child.

In 2007 it was Nominated for Best Rap Performance as a Duo or Group at the 49th Annual Grammy Awards, but lost to "Ridin'" by Chamillionare and Krayzie Bone. The RIAA certified it as Platinum in the U.S.
