See (Almost) Every Musician Who's Been in Megadeth

Here's (almost) every musician who's been an official member of Megadeth.

When you think of bands that have had a lot of different members, Megadeth surely come to mind. There've been over 20 musicians that have played in the band since Dave Mustaine formed it in 1983.

Fate had a helping hand in the formation of Megadeth. Mustaine never would've start it if he hadn't been fired from Metallica that same year. Lucky for him, his project also became very successful and was a pivotal part of the thrash metal scene.

David Ellefson joined on bass shortly after, and remained in the group until Mustaine disbanded it in 2002 after sustaining an injury to his arm that rendered him unable to play guitar. Ellefson returned again in 2010, but was let go in 2021 while they were working on  The Sick, The Dying... and the Dead!. 

Aside from Mustaine and Ellefson, Megadeth had a revolving cast of musicians throughout its existence. We compiled a gallery of most of them below and listed them in chronological order from when they first joined. The years they were in the band are listed next to their names, since some later returned to the group.

In August of 2025, Megadeth revealed that their forthcoming 17th studio album and its accompanying tour will be their last. We don't have any details about the album's title or release date as of yet, but as they wrote in their social media post, "the end is near."

Scroll through the gallery below to revisit Megadeth's storied history. Please note that we couldn't find images for some of the musicians credited as having been in the band. Therefore, the list is missing some of its early members, such as Greg Handevidt and Dijon Carruthers.

We also didn't include photos of any session musicians either as they weren't actual members of the band aside from their studio contributions.
