The collection of stories from more than 50 creators is inspired by the current Occupy Wall Street protests.
Moore recently spoke out against fellow creator Frank Miller's verbal attack on the protesters.
"It's fair to say that Alan Moore and David Lloyd are unofficial godfathers of the current protest movement," Occupy Comics organiser Matt Pizzolo told Wired.com.
"It's really amazing to see two creatives whose work was inspiring to street protesters join a creative project that is inspired by the street protesters. It's a pretty virtuous cycle."
Moore will write a prose piece for the anthology, which is being funded through Kickstarter.
A 'making of' documentary is also being produced by Patrick Meaney, the director of Grant Morrison: Talking With Gods and Warren Ellis: Captured Ghosts.
Miller recently wrote a blog post calling the Occupy protests a "bowel movement" and the protesters a "pack of louts, thieves, and rapists".
While fellow writer Mark Millar defended Miller, Moore said that the Occupy movement is "a completely justified howl of moral outrage".
The Occupy Comics anothology also includes work from Michael Allred, Darick Robertson, Douglas Rushkoff, Ben Templesmith, Si Spurrier, Dean Haspiel, Amanda Palmer, JM DeMatteis, Steve Niles, Dan Goldman, Charlie Adlard, Susie Cagle, Shannon Wheeler, Molly Crabapple, Ryan Ottley, Joshua Dysart, Joseph Michael Linsner, Joe Keatinge, B Clay Moore and Joshua Hale Fialkov.
