"Tell Me Something Good" is a song by Rufus, written by Stevie Wonder and released in 1974. This was the first and only hit credited to Rufus, as once singer Chaka Khan's voice became the focus of the group, they changed their name to "Rufus featuring Chaka Khan" for their next album.^[3] The single was a hit in the United States, peaking at number three on the Billboard Hot 100 and spent one week at number one on the Cash Box Top 100.^[4] It was among the earliest hits to use the guitar talk box, by Tony Maiden.^[5]

The record was produced by the band with Bob Monaco.^[6]

The song has been described as having ".. rude metallic guitar" (by Al Ciner) and ".. a beautiful bass, clav and heavy breathing groove." The song can be difficult to count as there is an off-count into the verse. The first note is on the "and of four."^[7]

Jason Elias of AllMusic described the song as "a rare instance of an artist like Stevie Wonder giving away a tune that he could have had a big hit with himself."^[8]

On July 5, 1974 the band played the song on The Midnight Special^[9] and on September 7, played the song, along with "You Got The Love", on Don Cornelius' show Soul Train,^[10]

Rufus won the Grammy Award for Best R&B Vocal Performance by a Duo, Group or Chorus for the song at the 17th Annual Grammy Awards in 1975.
