Electronic Design Hannover was a German game developer, presumably based in Hannover, Germany, affiliated with German publisher and developer reLINE Software.

EDH is credited for two games: Legend of Faerghail (1990, Atari ST) and Mit Jeans und Hellebarde (1989, Commodore 64).

Not much else is known of the company, but its personnel appear to have worked at reLINE in the following years.
