Konrad "Conny" Plank (May 3, 1940 – December 18, 1987) was a German record producer and musician. He was born in Hütschenhausen. His creativity as a sound engineer and producer helped to shape many innovative recordings of postwar European popular music, covering a wide range of genres including progressive, avant-garde, electronic music and krautrock. His immense catalog of work has greatly influenced modern studio production and engineering techniques.

As a musician, Plank is credited on albums by Guru Guru, Kraan, Cluster, Liliental and Os Mundi. He collaborated with Dieter Moebius on five Moebius & Plank studio albums recorded between 1979 and 1986. The Moebius & Plank sound foreshadowed techno and electronica and influenced many later musicians.
