Dżem is a Polish blues-rock band.

Their history dates back to the mid-1970s, although their first records were released in the mid-1980s. Their style varies between blues, southern rock, and hard rock. Their late vocalist - Ryszard Riedel [d. 1994 from heart failure caused by heavy drug addiction] - was an iconic figure in the history of Polish rock, followed by a nationwide cult similar to Jim Morrison's. His replacement - Jacek Dewódzki - sang on three albums in the second half of the 1990s, before being replaced by the more blues-orientated current singer, Maciej Balcar, in 2001. Their first album with Balcar, called 2004, was released in September 2004.

After the tragic death (in a car crash) of the pianist Pawel Berger in January 2005, the band took a break for four months, before returning to full activity with a new pianist, Janusz Borzucki, in May 2005. Dżem's newest studio album and the first with the current line-up, Muza, was released in November 2010.

The current line-up of the band features:

Maciej Balcar (since 2001)

Jerzy Styczyński (since 1979)

Adam Otręba (since 1973)

Beno Otręba (since 1973)
