The Serni was a short river of southern Gondor; it rose beneath the eastern White Mountains, and flowed southwestward through Lebennin until it met the River Gilrain at Linhir.
The name Serni is an "adjectival formation" deriving from Sindarin sarn ("small stone, pebble").
The name of the river is spelled Serni in the maps of The Lord of the Rings. In the footnote 1 of the Preface of The Adventures of Tom Bombadil it is spelled Sernui.
