Blue Sky Studios is an American CGI-animation studio which specializes in high-resolution, computer-generated character animation and rendering. It is owned by 20th Century Fox and located in Greenwich, Connecticut. In addition to their feature-length animated films, including the Ice Age series, Robots (2005), Horton Hears a Who! (2008), and Rio (2011), Blue Sky has worked on many high-profile films, primarily in the integration of live-action with computer-generated animation.

Blue Sky was founded in February 1987 by Chris Wedge, Carl Ludwig and four other artists and technicians who had previously worked on the Disney film Tron while employed at MAGI/Synthavision. Throughout the late 1980s and 1990s, the studio concentrated on the production of television commercials and visual effects for film. Some of the more memorable commercials that Blue Sky worked on during this time period were a Chock Full O' Nuts spot with a talking coffee bean, and an intro for a Nickelodeon block called Nicktoons that featured the show's mascot, Nick Boy, realized as human-shaped orange goo. Using their proprietary animation pipeline, the studio produced over 200 spots for clients such as Chrysler, M&M/Mars, General Foods, Texaco, and the United States Marines.
