Dragon Knight 4 (ドラゴンナイト４) is a role-playing video game developed by ELF Corporation and released only in Japan for several platforms between 1994 and 1997.

In 1994, the game first became available for PC MS-DOS, NEC PC-9801 and X68000, with a censored version ported to the Super Nintendo Entertainment System in 1996 and later to the PC-FX, PlayStation and Sega Saturn in 1997.

Allies and enemies are both separated into statistically distinct classes: swordsmen, archers and sorcerers, with certain armour and weaponry being appropriate to each.

The central character of Dragon Knight 4 is Kakeru (カケル) (voiced by Megumi Ogata), the son of Yamato Takeru, the protagonist of the earlier games in the series, and the sorceress Luna.

The second, two-volume novel was written by Youko Kagura, illustrated also by Masaki Takei, and released by Kill Time Communication in 2007–2008.
