The Punisher War Journal is the title of two Marvel Comics comic book series featuring the character Frank Castle, also known as the Punisher. The first volume, published from 1988 to 1995, was spun off of a self-titled series featuring the vigilante's exploits.
After this, the character went through a number of incarnations in Marvel's imprints, such as Marvel Knights and MAX, that were outside of regular Marvel continuity. The second volume of War Journal, published between 2007 and 2009 by writer Matt Fraction, placed the character firmly in the ongoing Marvel Universe inhabited by superheroes such as the Avengers and Spider-Man, and super-villains such as Doctor Doom and the Masters of Evil. This was reflected in the series by tying into crossover events of the Marvel Universe proper, including "Civil War", "World War Hulk", and "Secret Invasion".
