The River Flows: Anthology Vol. 1 is a progressive rock 4-CD album by Iona, released in 2002. It is a box set collection of their first three studio albums with some re-recording plus a fourth disc which is a collection of additional material from throughout the years. The band's first album, Iona, has the re-recorded tracks and each of the first three is subtly re-mastered.

CD 4 contains new and previously unreleased material including Iona's soundtrack from the BBC nature programme Snowdonia Realm of the Ravens (remixed and extended), jigs, reels, a new version of "Hearthquake" and other unreleased material.

(Note these musicians are those present for the 4th disc - see individual entries for the first three.)
