Pac-Man Championship Edition is a 2007 maze video game developed and published by Namco Bandai Games for the Xbox 360. It has since been released on several other platforms, including iOS, Android, and the PlayStation Portable as a PSP mini title available on the PlayStation Store (consequently playable on the PlayStation 3). It is an HD reimagining of Namco's original Pac-Man arcade game; players navigate Pac-Man through an enclosed maze, eating pellets and avoiding four ghosts that pursue him. Clearing an entire side of the maze of dots will cause a fruit item to appear, and eating it will cause a new maze to appear on the opposite side.

Development of Championship Edition was headed by director Tadashi Iguchi, alongside producer Nobutaka Nakajima and designer and the father of Pac-Man, Toru Iwatani, the original creator of Pac-Man — Championship Edition was the final game he designed. Unhappy with earlier attempts to remake Pac-Man for removing many of the common elements present in the original, the development team focused on taking the original concept and expanding on two core features: the game speed and new mazes, which they felt would be the best way to "modernize" it. Iguchi was not much of a Pac-Man fan, spending much of his time thinking about how hardcore Pac-Man fans would react to the game's new features and ideas. It was chosen to make the game feel like an arcade game, due to it being released for the Xbox Live Arcade service.

Backed by a large marketing campaign orchestrated by Microsoft and Namco Bandai, Pac-Man Championship Edition was well-received by critics. Publications commended the game for successfully translating the classic Pac-Man gameplay into a modern format, with its gameplay, soundtrack and online features also being praised. One critic labeled it as "the first true sequel to Pac-Man since Ms. Pac-Man". However, some disliked the lack of a multiplayer mode and for reusing enemy movement patterns in the original. It was remade by Chinese studio Mine Loader Software as Pac-Man Championship Edition DX and followed by a sequel, Pac-Man Championship Edition 2.

Like the original Pac-Man, the basic game play of Pac-Man Championship Edition consists entirely of navigating Pac-Man through a maze, eating dots, power pellets and bonus items (such as fruits, keys, and other objects), and avoiding the four ghosts that roam the maze as well. If Pac-Man is caught by a ghost, the player loses a life. Eating a power pellet causes the ghosts to turn blue, allowing Pac-Man to eat them and send them back to their home, where they re-emerge in their original form. An extra life is awarded after every 20,000 points earned.

However, there are several major differences from its original counterpart, making Pac-Man C.E. a faster paced game. Each maze is divided into two halves. Eating all the dots on one half causes a bonus item to appear on the other side, and eating the item causes a new maze to appear on the other half. Players can also collect additional power pellets to increase their powered up time and continue earning maximum points for eating ghosts. The game speed increases as the player scores points, and decreases when they lose a life. As opposed to levels, the game is played within a certain time limit, with players attempting to get the highest score possible.

The game features six modes: Championship, which is the basic five-minute mode, two ten-minute Challenge modes which affect the stage (such as increasing power pellet pickups or putting the maze in darkness) and three Extra modes (one five-minute and two ten-minute) featuring different mazes. The game also supports online leader boards.

The idea for the game that later became Pac-Man Championship Edition was conceived following the release of the original Pac-Man arcade game for the Xbox Live Arcade online service in 2006. Namco Bandai Games producer Nobutaka Nakajima noticed how the classic Pac-Man gameplay took place on a tall, vertical screen, in drastic comparison to the widescreen HD television sets most consumers have, alongside its "very low-resolution, old-school gameplay." With next generation video game consoles posing much more powerful hardware, the idea of a modernized remake of Pac-Man for HD televisions came into fruition. Nakajima became the project's producer, assisted by director Tadashi Iguchi and designer Toru Iwatani, the original creator of Pac-Man. Championship Edition was the last game that Iwatani designed. When the game was being idealized, the development team focused on the question: "We have all of this new technology and hardware and power. What would Pac-Man be like, taking this technology and putting it to the max?"

Nakajima felt that most remakes and sequels to Pac-Man stray too far from what he considered "the fundamentals of what made Pac-Man so great." With Championship Edition, he went back to the roots of the original to expand on its concept, while still keeping the game's core mechanics intact. Iwatani wanted the game to keep the simplicity of Pac-Man, as he felt that is what made the game fun and compelling. When the development team was discussing with Iwatani about the idea of the game, Namco Bandai was approached by Microsoft about a crossover promotional event centered around Pac-Man; with this in mind, the team focused on making the idea of players playing together a focal point for the game, wanting it to be full of excitement and action.
