The cycle of erosion was a model for stream erosion and landscape development proposed by William Morris Davis in the late 1800s. Davis' Stages in the fluvial cycle of erosion published in 1909 defined a young, mature, and old sequence in the development of river valleys and the landscape the rivers were eroding. The concept of peneplanation was a part of his model.

The model developed by Davis, though important in historical context, is currently considered only a first approximation. Developments in the sciences of geology and geomorphology, especially the plate tectonics revolution of the 1960s and 70s, have confirmed the preliminary nature of the model.
