Psychopathic Rydas is an American hip hop group based in Detroit, Michigan. Formed in 1999, the group consists of Psychopathic Records-associated rappers performing under alternate stage names in the style of gangsta rap. The group's current lineup consists of Insane Clown Posse's Joseph Bruce aka Violent J (Bullet) and Joseph Utsler aka Shaggy 2 Dope (Full Clip), Chris Rouleau aka Blaze Ya Dead Homie (Cell Block), and James Lowery aka Anybody Killa (Sawed Off). Lowery was on the albums Check Your Shit in Bitch! and Limited Edition EP in 2004, left the label and group in 2007, and returned in 2011 for the albums EatShitnDie and Backdoor Ryda EP.

Neme Encarnacion aka Myzery (Twin Gatz) was on the album Dumpin' in 1999. Rashaam Attica Smith aka Esham (Converse) was on the albums Check Your Shit in Bitch! and Limited Edition EP in 2004. David Hutto aka Boondox (Yung Dirt) was on the albums Duk Da Fuk Down, EatShitNDie, and Backdoor Ryda EP from 2007 to 2011.

Psychopathic Rydas reuses the beats of popular rappers within the genre without paying to license the original songs or requesting permission from copyright owners to use the music, effectively making their albums bootlegs and resulting in the releases becoming difficult to find in some markets. Psychopathic Rydas' debut album, Dumpin', was originally given away for correctly answering a series of trivia questions printed in the liner notes of Insane Clown Posse's album, The Amazing Jeckel Brothers. Twiztid stated via Twitter they parted ways with Psychopathic Records on December 12, 2012. Thus putting the future of the group in question. However in March 2013, Joseph Bruce commented on Twiztid's departure revealing that there was no animosity between Twiztid and Psychopathic and that Twiztid were still a part of Dark Lotus and Psychopathic Rydas.
