Plastic Letters is the second studio album by American rock band Blondie, released in February 1978 by Chrysalis Records.

The song was written by the band's second bassist, Gary Valentine, shortly before he left for a solo career prior to the recording of Plastic Letters; his departure necessitated Chris Stein playing bass on the album, as well as guitar.

The pink dress Debbie Harry wears in the cover art was designed by Anya Phillips.

The latter issue features the earliest demo of the band's future hit "Heart of Glass", then known as "The Disco Song".

The Globe and Mail wrote that "some of Blondie's hardness has been made pliable with curious arrangements and an attempt to make the band seem more formidable than it really is.
