30631 equal divisions of the octave (abbreviated 30631edo or 30631ed2), also called 30631-tone equal temperament (30631tet) or 30631 equal temperament (30631et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 30631 equal parts of about 0.0392 ¢ each. Each step represents a frequency ratio of 21/30631, or the 30631st root of 2.

30631edo is consistent in the 35-odd-limit and is a zeta peak integer edo.
