Diminutive Mysteries (Mostly Hemphill) is an album by saxophonist Tim Berne which was recorded in 1992 and released on the JMT label.

Alongside Berne's regular band is featured guest David Sanborn, in an outlier among his more mainstream R&B work.

The AllMusic review by Scott Yanow states: "This is certainly the most unusual David Sanborn recording to date.

Avant-gardist Tim Berne (heard here on alto and baritone) and the popular R&B star Sanborn (mostly leaving his trademark alto behind to play sopranino) share a great respect for altoist Julius Hemphill and the St. Louis free jazz movement... they perform seven often-emotional Hemphill pieces plus Berne's "The Maze."
