Jeff Matsuda (born 1970) is a Japanese American animator and concept and comics artist who served as the chief character designer for both Jackie Chan Adventures and The Batman and is the president and creative director of X-Ray Kid Studios. Matsuda was discovered by Rob Liefeld after submitting some Wildcats samples pages to Liefeld's Extreme Studios and Jim Lee's Wildstorm. However, Matsuda's first published artwork, depicting the X-Force character Cable, appeared in the letter art section of Wizard Magazine.
While at Extreme, he penciled issues of the Image Comics titles: Brigade, Team Youngblood, Youngblood Strikefile, Troll and New Men. Matsuda moved on to work for Marvel Comics beginning with some pages for X-Men Prime, which eventually led to runs on X-Factor and Wolverine in addition to work on individual issues of X-Men, Generation X, Avengers and some pinup drawings in X-Men Unlimited.
Matsuda was later reunited with Liefeld at Awesome Comics which published Kaboom, written by award-winning writer Jeph Loeb. The protagonist of the title featured a third spelling of its creator's first names, Geoff, though in Loeb's case, Jeph is actually short for Joseph.
