Abstract
The main contribution of our paper is to give a partial classification of the quasi-exactly solvable Lie algebras of first order differential operators in three variables, and to show how this can be applied to the construction of new quasi-exactly solvable Schrödinger operators in three dimensions.

Key words: quasi-exact solvability; Schrödinger operators; Lie algebras of first order differential operators; three dimensional manifolds.
