"No Class" is a song by the British heavy metal band Motörhead. It was released in 1979 in 7" vinyl pressings. The song first appeared on the 1979 album Overkill, and became one of the "cornerstones" of the classic 1981 live album No Sleep 'til Hammersmith. It is one of the band's "anthems".

It was available in three different covers, with either a picture of Lemmy, "Fast" Eddie Clarke or Phil "Philthy Animal" Taylor. The single also contains the B-side "Like a Nightmare", which can be found on the reissued versions of Overkill. The song was already a live track before it was recorded for Overkill.

Stylistically, the song is described as "get-down rock boogie". Critics have noted the similarities at the time between Motörhead's music and ZZ Top's, and the guitar riff in "No Class" is said to be "stolen" from ZZ Top's "Tush."

On Motörhead's 1999 live album Everything Louder than Everyone Else, before playing "No Class" Lemmy dedicated the song to long-time friend Wendy O. Williams, who had committed suicide the previous month.
