A sequence of events is isochronous if the events occur regularly, or at equal time intervals. The term isochronous is used in several technical contexts, but usually refers to the primary subject maintaining a constant period or interval (the reciprocal of frequency), despite variations in other measurable factors in the same system.

Isochronous timing differs from synchronous timing, in that the latter refers to relative timing between two or more sequences of events.
