Bis ( BISS, stylised in all lowercase) are a Scottish indie pop band composed of Steven Clark (Sci-Fi Steven), John Clark (John Disco), and Amanda MacKinnon (Manda Rin), formed in 1994. The band's name, rhyming with 'this', derives from "black iron skyline", a lyric from the song "Twilight of a Champion" by The The.

After releasing numerous EPs and three studio albums, The New Transistor Heroes (1997), Social Dancing (1999), and Return To Central (2001), the band broke up in 2003, but re-formed briefly in 2007 for a series of concerts. In 2009, they re-formed again and released the album data Panik etcetera (2014).

In 2019, the band's lineup returned to the original core three-piece and released the album Slight Disconnects. In 2021, the band self-released Low Level (A Return To Central Travel Companion), a CD consisting of previously unreleased material recorded during the Return To Central sessions. In October 2022, Systems Music For Home Defence was released, which Sci-Fi Steven has described as the band's "rave" album.
