Runnin' Off at da Mouth is the debut studio album by American rapper Twista, who was known at the time as Tung Twista. Released in 1992, it was Loud Records' first release and its only release distributed by Zoo. The album was released after Twista entered the Guinness Book of World Records as the world's fastest emcee.

"Mr. Tung Twista" was the sole single released from the album, though it failed to chart.

The Washington Post wrote that "Tung Twista does decelerate later in the album on some songs, but by then chances are listeners are already exhausted from listening to the rapper's exhaustive style."
