("Johnny") Ryan IV (born November 30, 1970 in Boston, Massachusetts) is an American alternative comics creator.
He created Angry Youth Comix, a comic book published by Fantagraphics, and "Blecky Yuckerella", a comic strip which originated in the alternative newspaper the Portland Mercury and now appears on Ryan's website.
He also created Pig Goat Banana Cricket, a TV show made jointly with Dave Cooper that Nickelodeon picked up.
He is now the story editor for Looney Tunes Cartoons.
In a throwback to the days of underground comix, Ryan's oeuvre is generally an attempt to be as shocking and politically incorrect as possible.
