Devil May Cry 4 is an action-adventure hack and slash video game developed and published by Capcom in 2008 for the PlayStation 3, Xbox 360 and Windows platforms. The game is the fourth installment to the Devil May Cry series. It later on generated a handheld version released on iOS, titled Devil May Cry 4: Refrain. Chronologically, the game is set between the original Devil May Cry and Devil May Cry 2.

The story follows Nero, a teenager possessing demonic powers who is on a mission to stop the series' main character, Dante, after he assassinates demons from the Order of the Sword including its leader. During the game, the player controls both Nero and Dante as they fight enemies in close combat using firearms, swords, and other weapons. Devil May Cry 4 was the first entry in the series to release for multiple consoles at the same time; during its development, Capcom focused on all versions achieving the same visual quality.

Critical reception to Devil May Cry 4 was positive, with praise aimed towards its challenging difficulty and the characters' special moves. However, it was also criticized for its backtracking and a troublesome camera. The game sold over 3 million units worldwide, becoming the series' best-selling title. It has also been adapted into a two-volume light novel by its original writer, Bingo Morihashi.

A remastered version of the game was released in June 2015 as Devil May Cry 4: Special Edition, which adds both English and Japanese voice tracks, improved visual effects and textures, in-game re-balancing, additional costumes, and 3 bonus playable characters: Vergil, returning from Devil May Cry 3, Trish, playable for the first time since Devil May Cry 2, and Lady, who makes her playable debut.
