Pope Adrian 37th Psychristiatric is a concept album by the band Rudimentary Peni.

The majority of the album was written while lead singer/guitarist Nick Blinko was being detained in a psychiatric hospital under section 3 of the Mental Health Act 1983.

The subject matter of the album relates to the delusions Blinko was experiencing at the time, particularly the idea that he was "Pope Adrian 37th" — a reference to Pope Adrian IV.

[5] Adding to the album's unique sound, the pseudo-latinized phrase "Papas Adrianus" (Pope Adrian) is looped and can be heard in the background through the entire album.

Blinko provided the artwork for the album.
