An interfluve is a narrow, elongated and plateau-like or ridge-like landform between two valleys.^[1][2] More generally, an interfluve is defined as an area of higher ground between two rivers in the same drainage system.^[3]

These landforms are created by earth flow ("solifluction"). They can also be former river terraces that are subsequently bisected by fluvial erosion. In cases where there is a deposit of younger sedimentary beds (loess, colluvium) the interfluves have a rounder and less rugged appearance. A consequence of interfluve formation is the so-called "interfluvial landscape."^[2]
