Teufel Audio (referred to as Teufel, German: Lautsprecher Teufel) is a German manufacturer of audio products such as loudspeakers, headphones, hi-fi and home cinema systems.

Teufel was founded in Berlin in 1979 by Peter Tschimmel. In the initial phase, the company produced and sold loudspeaker kits consisting of ready-made crossovers, drivers and cabinet components. The first products were loudspeaker sets. In 1990, Teufel changed its distribution model, from specialist and retail outlets to direct sales via catalogue.

In 2006 private equity firm Riverside acquired Teufel from founder Peter Tschimmel. A year later, in 2010, private equity firm HgCapital acquired the company from Riverside. At the same time, Teufel integrated the Berlin-based start-up Raumfeld, which had been developing and selling multi-room streaming speakers since 2008. In summer 2018, French private equity company Naxicap took over the company. Since March 2020, Sascha Mallah has led the company as sole Managing Director.

In 2024, Teufel and Fender jointly launched a speaker line.
