Thunder Perfect Mind is an album by the English experimental group Current 93, released on 28 July 1992. It contains two tracks based on the Gnostic poem The Thunder, Perfect Mind, which also gave the album its name. Thunder Perfect Mind has a companion album by the same name recorded by Nurse With Wound, released at the same time, though the two albums have little in common with each other musically.

The album is one of David Tibet's more personal records, with several songs dedicated to friends, colleagues and people he had met. "All The Stars Are Dead Now" consists of a startling prophecy given to Tibet in a dream by William Blake, while the epic "Hitler As Kalki (SDM)" is dedicated to "my father, who fought Hitler." The liner notes indicate that some believed Hitler was Kalki, the tenth and final incarnation of Vishnu, who would destroy the cosmos upon a white horse at the end of each world cycle.

Original pressings contained a portrait of David Tibet's face, while later pressings contained a drawing of a startled cat drawn by Louis Wain. On its 2003 re-release, the cover sported Tibet's face again, though a second re-issue a year later on Durtro Jnana Records (due to World Serpent's sudden disappearance) featured a beige-toned pattern across the portrait. These later pressings included a bonus disc titled The Thunder, Perfect Mind which contained outtakes and alternate mixes of songs, as well as five live tracks recorded in Paris on 15 December 1990. All of the studio tracks save "Red House" and an acoustic version of "Anyway, People Die" had previously appeared on Emblems: The Menstrual Years.
