"Don't Let's Start" is a song by the alternative rock band They Might Be Giants, from their 1986 eponymous debut album.

The lyrics of "Don't Let's Start" include a number of dark, pointed statements, such as "everybody dies frustrated and sad, and that is beautiful."

John Linnell has repeatedly insisted that some of the song's lyrical twists, though pondered extensively by fans, were constructed to complement the melody and were not necessarily meaningful.

The band is featured wearing tall hats which, according to John Flansburgh on Tumblr, consist of "a large piece of semi-rigid cardstock (cut in a little arc) covered with a light bolt of red velvet fabric from a fabric store."

His face also appears on the "Don't Let's Start" CD single, and it has frequently been used in other contexts associated with They Might Be Giants.
