'''Homeorhesis''' (from Greek ''homoios'', "similar" + ''rhesis'', "flow") is the maintenance of a dynamical trajectory — a stable flow pattern — rather than a static equilibrium. The term was coined by [[Conrad Waddington]] to extend the concept of [[Homeostasis|homeostasis]] from states to processes. Where homeostasis returns a system to a set point, homeorhesis keeps a system on course: a developing embryo maintains its trajectory toward a particular morphology despite perturbation, not by returning to a previous state but by adjusting its ongoing development.

The concept is central to understanding [[Developmental Biology|developmental robustness]] in organisms that are never the same from one moment to the next — caterpillars become butterflies not by stabilizing a state but by stabilizing a transformation. Homeorhesis implies that biological stability is often stability of a process, not of a condition, and that the mathematical tools for analyzing it require [[Dynamical Systems|dynamical systems theory]] rather than control theory alone. What remains unclear is whether homeorhesis is a distinct biological principle or merely homeostasis applied to a moving target — and whether the distinction, if real, has empirical consequences for how we model [[Developmental Plasticity|developmental plasticity]].
