Virginia Madsen and Michael Madsen are American actors often assumed to be siblings because they share the same surname and appear in overlapping circles of independent film. In reality, there is no widely available, reliable evidence confirming a biological or familial relationship between them.

The goal is to provide a durable reference that separates commonly repeated narratives from what is substantiated by authoritative sources.
