Nick Jennings is an American director, artist, writer, and producer best known for his work on the Nickelodeon shows Rocko's Modern Life and SpongeBob SquarePants, as well as the Cartoon Network series Adventure Time. He has also worked as a background artist for many animated television series.
In 1988, Nick Jennings did the layouts for A Pup Named Scooby-Doo while working at Colossal Pictures at San Francisco.
Jennings was the executive director for The Powerpuff Girls (co-executive producer: Bob Boyle). Animation Magazine reported that the series won "two Emmy Awards along with five nominations and countless other honors and accolades."
Jennings partnered with the Exceptional Minds program where he mentored adult animation artists who were on the autism spectrum. Jennings remarked that the program helped these artists to better understand the importance of deadlines and scheduling within the studio environment, and to learn strategies for a successful career as an animator.
In late 2013, it was announced that Jennings, along with several other members of the Adventure Time staff, had been nominated for an Annie Award for "Outstanding Achievement, Production Design in an Animated TV/Broadcast Production." On July 31, 2014, Jennings had won an Emmy for "Outstanding Individual Achievement In Animation" for his work on the Adventure Time episode "Wizards Only, Fools."
