Mega Man (known as Rockman in Japan) is a Japanese science fiction video game franchise created by Capcom, starring a character named "Mega Man". The original game was released for the Nintendo Entertainment System in 1987, and spawned a franchise that expanded to over 50 games on multiple systems. As of October 2023, the series has sold 41 million units worldwide.

The main series consists of eleven games, the standalone Mega Man & Bass, the spin-off Game Boy series (released in Japan as Rockman World), and various ports, remakes, and compilations. The core games in the franchise have all been set in a single continuity; the storyline of the "classic" series is succeeded by the Mega Man X, Mega Man Zero, Mega Man ZX, and the Mega Man Legends series. This timeline excludes the spin-off Mega Man Battle Network and Mega Man Star Force series, both of which take place in an alternate universe where the internet flourished rather than robotics.

The original Mega Man series, dubbed Classic Mega Man marks the start of the franchise, released on the NES on December 17, 1987. In the original series, Mega Man is a robot originally named Rock (nicknamed “Mega” in later installments), created as a lab assistant by the scientist Dr. Light with Dr. Wily as his partner. Following treachery by Dr. Wily in which he reprogrammed most of Dr. Light's robots, Rock volunteered to be converted into a fighting robot to defend the world from Wily's violent robotic threats, thus becoming Mega Man.

Mega Man is a side-scrolling action platformer. The player character must fight through the levels using Mega Man's "Mega Buster"—a cannon attached to his arm—to shoot the robotic enemies inhabiting his environment. When Mega Man was released in 1987, the characteristic that made it revolutionary was the choice given to the player of which robot master to attempt first. After defeating a Robot Master—the boss of a level—Mega Man gains the ability to use that Robot Master's special weapon. Each Robot Master represents a specific element or object, with bosses such as Fire Man, Ice Man, Guts Man, Cut Man, Elec Man, and Bomb Man. The weapons Mega Man gains share the theme of the defeated boss. After defeating all of the Robot Masters, Mega Man travels to a multi-stage fortress to confront Dr. Wily, the person responsible for the robotic enemies' destructive acts. In the fortress, Mega Man fights past new bosses, clones of the game's Robot Masters, and Wily himself, who is usually in a large multi-phase war machine.

Enemies are weak to at least one weapon; for instance, Fire Man will take more damage from Ice Man's weapon than from other weapons. This concept draws inspiration from rock-paper-scissors. Robot Master levels can generally be completed in any order, resulting in a strategic hallmark of the series: determining the best order to defeat bosses and earn weapons. Sequels of Mega Man games contain new enemies alongside familiar ones, new bosses, new weapons, and occasionally new gadgets that Mega Man could use. Starting from Mega Man 3, Rush—Mega Man's trusty robot dog companion became a series mainstay, and later installments would provide Rush abilities for Mega Man to use. Later installments of the game give the player the option of commanding other player characters with different abilities, such as Proto Man, Duo, and Bass.

The Classic series has not reached a definite conclusion. Originally developed for the NES, the original Mega Man series experienced graphical improvements in fourth and fifth-generation installments. The series had no games developed for sixth-generation consoles but returned in the seventh generation purposely sporting graphics, sound, and gameplay similar to the original NES games to inspire a nostalgic look and feel, distributed as downloadable content instead of retail games like the previous installments.

On December 4, 2017, Capcom announced that a new game in the classic series, Mega Man 11, would be released in late 2018. Unlike Mega Man 9 and 10, this game makes a return to the modern era, featuring Mega Man in a 2.5D environment, with 3D cel-shaded graphics, and is presented in a widescreen aspect ratio. When using a special weapon, in addition to changing colors, Mega Man's armor also changes appearance.
