1983 equal divisions of the octave (abbreviated 1983edo or 1983ed2), also called 1983-tone equal temperament (1983tet) or 1983 equal temperament (1983et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 1983 equal parts of about 0.605 ¢ each. Each step represents a frequency ratio of 2^1/1983, or the 1983rd root of 2.

This EDO is consistent to the 17-odd-limit, but is most notable in the 2.3.7.11.13 subgroup, with very low relative error.
