Dragon Spirit is a 1987 vertically scrolling shooter video game developed and published by Namco for arcades; in North America, it was distributed by Atari Games. Controlling the dragon Amur, the player must complete each of the game's nine areas to rescue the princess Alicia from the demon Zawell. Similar to Namco's own Xevious, Amur has a projectile weapon for destroying air-based enemies and a bomb for destroying ground enemies. It ran on the Namco System 1 arcade board.

Music for the game was composed by Shinji Hosoe and designed by Tatsuya Ishikawa. Hosoe, previously a graphics artist for Namco, was allowed to work on the music himself due to most of the company's composers working on Genpei Tōma Den. However, much of his work was accidentally wiped from the hardware midway through development, forcing him to start over. Ishikawa previously created character artwork for Rolling Thunder, being assigned to the project after taking an interest in the enemy designs. The game was dedicated to Shouichi Fukatani, a Namco programmer who had died a few years earlier in 1985 and worked on many of the company's older games, such as Dig Dug and Super Pac-Man.

The game was ported to several home systems, including the Sharp X68000, TurboGrafx-16 and Atari ST, and is featured in various Namco compilations. The arcade version of Dragon Spirit was met with positive reviews from critics for standing out amongst other shooter games, being praised for its Paleozoic setting, graphics and soundtrack. Home versions were met with a more mixed reception, being criticized for its high difficulty and inferior graphics and music. It was followed by two sequels, Dragon Spirit: The New Legend (1988) and Dragon Saber (1990). A ShiftyLook webcomic adaptation of the game was also produced.

Dragon Spirit is a vertically scrolling shooter where the player controls the dragon Amur in his effort to rescue the princess Alicia from the serpent demon Zawell. Amur can move in eight directions and has access to two weapons; a flame projectile to destroy air-based enemies, and a bomb to destroy ground-stationed enemies, similar to Namco's Xevious. Amur can take two hits before dying, indicated by a life bar at the bottom-left of the screen. Amur can use bombs to destroy eggs found on the ground of some stages, which will award one of two powerup items; a blue orb that will give Amur an extra head, granting him additional firepower, or an orange orb that will strengthen Amur's shots when three are collected.

The game features nine stages, which include large rivers, volcanoes, glaciers and jungles. Dying halfway through a stage will start the player at a checkpoint. At the end of each stage is a boss that Amur must fight in order to progress to the next stage. Amur can sometimes find special orbs throughout the game that can grant him additional abilities, such as a homing shot, a multi-shot, and the power to shrink down in size to evade bullets. The game's opening cutscene shows Amur atop a mountain raising his sword in the air, with lightning striking it and transforming him into his dragon form. If the player makes it to the end of the ninth level and defeats Zawell, Princess Alicia will be seen in captivity behind glass, which shatters as she yells "Amur!". The dragon then retransforms into human form and embraces Alicia, and an end scene is shown where the people of the kingdom are celebrating peace and prosperity now that Zawell's reign of terror is over.

Dragon Spirit was released in Japan by Namco on May 15, 1987, later licensed to Atari Games for release in North America. The game's music was composed by Shinji Hosoe, originally a graphic designer for the company. After asking Wonder Momo composer "Yudate" how to add music to the game code, he inserted many of his tracks during his own time — once the development team behind the game found out, he was automatically assigned as the game's composer. During its development, Namco was low on composers as many of them went to work on Genpei Tōma Den, allowing Hosoe to be able to compose the music himself.

Graphics were created by Tatsuya Ishikawa, who had previously produced character artwork for Rolling Thunder — after taking interest in the game's enemy designs, the team assigned him as the lead artist. Ishikawa listened to Hosoe's music when he was low on ideas for enemy or background designs. Hosoe's music was accidentally wiped from the hardware around midway through the development process, forcing him to start over. After the first set of arcade boards were released, Hosoe remade the game's music in hopes it could be reused for a re-issue of the hardware, but his idea was scrapped by Namco due to high production costs.

In North America and Europe, Dragon Spirit was ported to several home consoles and computers, including the Atari ST, Commodore 64, Amiga, ZX Spectrum and Amstrad CPC. In Japan, Namco ported the game to the Sharp X68000 and PC-Engine, the latter being published in North America by NEC for the TurboGrafx-16. Dragon Spirit is included in several Namco video game compilations, such as Namco Museum Vol. 5 (1997), Namco Museum 50th Anniversary (2005), Namco Museum Virtual Arcade (2008) and Namco Museum Essentials (2009). The TurboGrafx-16 conversion was digitally re-released onto the Wii Virtual Console in 2007, while the arcade version was released in 2009 exclusively in Japan. A version for Japanese mobile phones was released in 2003. An arcade version of Dragon Spirit was released under the Arcade Archives label for the Nintendo Switch and PlayStation 4 in 2022.
