Secret Affair are a mod revival band, formed in 1978 and disbanded in 1982 during which period their work is predominantly best-known. They reformed in 2002 and have since then produced an album in 2012.

The mod revival was a subculture that started in the United Kingdom in the late 1970s and later spread to other countries. The mod revival's mainstream popularity was relatively short, although its influence lasted for decades. The mod revival post-dated a Teddy Boy revival, and mod revivalists sometimes clashed with Teddy Boy revivalists, skinhead revivalists, casuals, punks and rival gang members.
