OctaDist is computer software for crystallography and inorganic chemistry program. It is mainly used for computing distortion parameters of coordination complex such as spin crossover complex (SCO), magnetic metal complex and metal–organic framework (MOF).

The program is developed and maintained in an international collaboration between the members of the Computational Chemistry Research Unit at Thammasat University,{{cite web|url=https://sites.google.com/site/compchem403|title=Computational Chemistry Research Unit Homepage|website=sites.google.com/site/compchem403}} the Functional Materials & Nanotechnology CoE at Walailak University{{cite web|url=https://www.funtechwu.com/|title=Functional Materials & Nanotechnology CoE Homepage|website=www.funtechwu.com}} and the Switchable Molecules and Materials group at University of Bordeaux.{{cite web|url=http://www.icmcb-bordeaux.cnrs.fr/spip.php?rubrique85|title=Switchable Molecules and Materials group Homepage|website=www.icmcb-bordeaux.cnrs.fr/spip.php?rubrique85}}

OctaDist is written entirely in Python binding to Tkinter graphical user interface toolkit. It is available for Windows, macOS, and Linux. It is free and open-source software distributed under a GNU General Public License (GPL) 3.0.
