Native to much of the Northern Hemisphere and introduced throughout much of the Southern Hemisphere. In Victoria, a widespread species of wet or low-lying, open sites, particularly in the west, occasionally growing partly submerged and then the stems commonly long and rooting freely from nodes.

Alopecurus australis was described as an indigenous Australian species, but it is generally agreed that the plant represented by that name is not specifically distinct from A. geniculatus and was an early introduction into this country.
