"Tree Trunk" is a song recorded and released in 1972 by The Doors.
"Tree Trunk" was recorded by the surviving members of The Doors as they assembled material for their second and final album, Full Circle, following the death of Jim Morrison. "Tree Trunk" was released as a B-side for the "Get Up and Dance" single released by Elektra Records in July 1972, and was thus on the penultimate Doors single release.
