**590 equal divisions of the octave** (abbreviated **590edo**), or **590-tone equal temperament** (**590tet**), **590 equal temperament** (**590et**) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 590 equal parts of about 2.03 ¢ each. Each step of 590edo represents a frequency ratio of 2^{1/590}, or the 590th root of 2.

590edo has the same tuning as the 118edo in the 5-limit and provides a good correction for the harmonics 7, 11, and 13, altogether being consistent in the 15-odd-limit. Among the 118th-octave temperaments, it by definition tunes parakleischis as well as centenniamajor in the 590ee val.

Besides that, it is a tuning for the quintaschis temperament in the 7-limit.
