RPG Maker 2003 (also known as RM2k3) is the third entry in the series of RPG Maker programs by ASCII. It is a video game creation program like other games in the series. It was released December 18, 2002, two years after its predecessor RPG Maker 2000. Its successor is RPG Maker XP, which was released in 2005.

Eventually, the program was translated into English illegally by RPG Advocate. On July 7, 2015 the Humble Game Maker Bundle went live, including this program, which is where it was first officially released in English. It is available on Steam for $19.99.


Based on RPG Maker 2000, it builds apon the old RPG Maker 2000 features and includes new features such as an improved default tileset, a new third person side-view active battle system, and additional database options. Most of the features present in RPG Maker 2000 are in RPG Maker 2003. It is also able to convert RPG Maker 2000 games into RPG Maker 2003 games after the database is accessed. This makes the game have features that RPG Maker 2003 has, such as the side view battle system, however, this makes it impossible to open it in RPG Maker 2000 again as it cannot convert RPG Maker 2003 games back into RPG Maker 2000 games.

The database now includes customization options for customizing the side view battler's animations.

The 2015 release of RPG Maker 2003 uses RPG Maker 2009 Ultimate DLLs for games updated to the newer versions, which adds support for 1000 images on screen at once, instead of the 50 in previous versions. It also includes the ability to resize windows such as the database and event windows.
