Klamydia (Finnish language for Chlamydia) is a punk rock band from Vaasa, Finland. The band's name was chosen because it was the worst name coming to their mind. The band was assembled in year 1988, and it has been continuously active since then.

Klamydia has always been renowned as a humour-band, but they have a lot of songs criticising society, and other songs about serious subjects, like incest as well as love songs.

Klamydia has also gained some popularity in Germany, where they have toured and released records.
