The DG-800 series comprises a family of 15 metre and 18 metre single-seat glider and motorgliders produced by Glaser-Dirks since 1993 and by DG Flugzeugbau GmbH after 1997. It is the successor to the DG-400 and the DG-600 models.

The DG-800 was planned primarily as a powered self-launching sailplane. In the meantime it has spawned many variants, differentiated by the type of powerplant (Rotax, Midwest or Solo), the span extensions (15 metre, 18 metre, both in variants with or without winglets), maximum allowed take-off mass, etc.

The newest model is the DG-808C, a self launching sailplane with Solo engine and the new designed "DEI-NT" Engine Control System.

There are also unpowered variants, the DG-800S and DG-808S, aimed at competition flying. These pure glider variants have a shorter and lighter fuselage built in the moulds of the DG-600 and allow a broader range of wing loadings.
