Current board member Mellody Hobson will succeed Enrico, according to a statement from the animation studio, which did not disclose reasons for Enrico's resignation.
Enrico, 67, has served as DreamWorks Animation’s chairman since 2004. He is a former chief executive of PepsiCo Inc., where he spent 31 years.
"Roger has been an invaluable leader to our board of directors and his guidance helped put DreamWorks Animation on a path to success from Day 1," DreamWorks Animation Chief Executive Jeffrey Katzenberg said in a statement.
