This is a list of all known Renegade Space Marine Chapters and Warbands that are considered renegades against the Imperium for reasons other than Chaos worship.
In the 10,000 years since their creation, many Space Marines have been declared as renegades from the Imperium. By far the most infamous and numerous of these are the Chaos Space Marines, but there are some forces who are considered renegades against the Imperium for reasons other than the worship of Chaos (although it should be noted that many such Chapters later succumbed to worship of the Ruinous Powers).
It should be noted that some Chapters have changed their names during their history and may be represented on this list more than once under different titles.
