Mompha propinquella is a moth in the family Momphidae found in Europe.

The forewings are dark leaden fuscous, with several small scattered orange ferruginous spots on the dorsal half; an ochreous-white triangular blotch on base of dorsum, almost touching costa at base; one or two white dots beyond this; three black scale-tufts towards dorsum, and three others above them; a white and ferruginous line from costa before middle running round central tuft ; a small white tornal spot and larger costal spot beyond it, disc near them suffused with ferruginous.

The larva is brown, marbled with pale; head and plate of 2 black: in blotches in leaves of Epilobium hirsutum.
