The German Association for Mathematical Logic and for Basic Research in the Exact Sciences (German: Deutsche Vereinigung für mathematische Logik und für Grundlagenforschung der exakten Wissenschaften; DVMLG) is the learned society representing the interdisciplinary research area of Logic (within the disciplines of Mathematics, Philosophy, Computer Science, and Linguistics) in German-speaking countries.

It was founded in 1962 by Wilhelm Ackermann, Gisbert Hasenjaeger, Hans Hermes, Jürgen von Kempski, Paul Lorenzen, Arnold Schmidt, and Kurt Schütte.

Biannually, the DVMLG organises the Colloquium Logicum, an international research conference in logic.

As part of these celebrations, the DVMLG organised a theatre tour of the University Players Hamburg performing Hugh Whitemore's play Breaking the Code in Germany and the Netherlands.

[12] Since 2024, the DVMLG awards the Ernst Zermelo Ring, an honour given every four years to a researcher in the foundations of mathematics who had a sustained influence on the development of the field and is expected to continue to remain active and influential.
