Karl Michael Koch (September 15, 1969) is a general assistant to American rock band Weezer and "unofficial fifth member" of the ensemble.

Since the band's inception he has assumed multiple different roles, including roadie, concert photographer, webmaster, social media manager, archivist, historian, and art director. Drummer Patrick Wilson said in 2005, "[the band] wouldn't be here if it wasn't for Karl."

Koch established and operates Weezer's official website and social media pages, on which he publishes his band news column Karl's Corner. The band's early adoption of the internet, spearheaded by Koch, is cited as a reason for their return to popularity after the hiatus that followed Pinkerton. Entertainment publications frequently utilize Koch's insider knowledge and photography (directly or via Karl's Corner) when writing about the band.

In addition to his work with Weezer, Koch releases his own music under the moniker Karlophone and has worked closely with Wilson's band The Special Goodness.
