Harmonic Disorder is an album by American jazz pianist Matthew Shipp recorded in 2008 and released on Thirsty Ear's Blue Series.

In his review for AllMusic, Thom Jurek states "The title Harmonic Disorder may read like this is one of Shipp's more intense outings, but the truth is, while it has wonderfully fiery moments, this is an intimate recording filled with new ideas, humor, depth, and warmth.

"[1] The Down Beat review by Peter Margasak notes that "While the pianist is in constant motion here, there’s a sense of patience and restraint that his early work lacked.

"[3] The All About Jazz review by John Sharpe states "The trio's wares here are spread over 14 tracks, with only three cuts breaking the five-minute barrier, in a program a shade under 55 minutes.

"[4] The PopMatters review by Will Layman states "All across Harmonic Disorder, Matthew Shipp is finding ways to blend his envelope-pushing with the sense of conventional order that reigned in piano trio music for a few decades.
