Civil War is a Marvel Comics summer 2006 and winter 2006/2007 crossover event based around a core limited series of the same name written by Mark Millar, and penciled by Steve McNiven. The work builds upon events appearing in previous Marvel crossovers, particularly Avengers Disassembled, House of M and Decimation. Some story elements are the result of the limited series Secret War. The tagline for the series is Whose Side Are You On?
