Wavering Radiant is the fifth and final full-length album by American post-metal group Isis, released by Ipecac Recordings in 2009 and produced by Joe Barresi. The band split just over a year after its release. The album continues Isis' history of lengthy songwriting, yet presents a slight departure from the soft-loud dynamics and post-metal aesthetic which characterized previous releases.

Reviewers noted a continued increase in melody from previous releases, and many were quick to note an increased prominence of keyboardist Bryant Clifford Meyer's work, using a Hammond B3 organ. In keeping with Isis' retinue of concept albums, a thematic strand runs throughout, dealing with dreams and Jungian psychology. Critical appraisal was largely positive, with some critics deeming it Isis' finest album; it also appeared on a handful of best-of lists at the close of the year. Commercially, it was Isis' most successful release ever, breaching the Billboard 200 for the first time and gaining international chart presence. It was ranked in the year-end lists by a number of reputed publications. To promote the album, Isis embarked on a world tour and shot a music video for the sixth track "20 Minutes/40 Years."
