Megadef is the second album by Los Angeles underground rap group Styles of Beyond, which was released on Spytech Records on September 9, 2003, after their 1998 installment 2000 Fold.

Mike Shinoda and Divine Styler, who proved to be the backbone of their debut album, were not present for this installment.

The sixth and final single from the album, "Bleach", was also included in the first mixtape We Major by Shinoda's side project Fort Minor, as a Jimi remix.

In a review by Steve 'Flash' Juon the album is explained as, Hailed as an underground classic, "2000 Fold" took us to styles beyond average hip-hop, no pun intended.

The duo seemed to delight in challenging the conventions of rap with every word, by turns imagining themselves as fly secret agents that could out bomb James Bond then in the next breath having to beg for a dollar for gas.
