Darwinia wittwerorum, commonly known as Wittwer's mountain bell,[2] is a plant in the myrtle family Myrtaceae and is endemic to a small area in Western Australia.

An erect, spindly shrub with fine leaves and hanging groups of flowers surrounded by leaf-like bracts, it is one of the darwinias known as mountain bells.

Wittwer's darwinia is an erect shrub with a single stem growing to a height of 60–80 centimetres (20–30 in).

[2][3] The first formal description of D. wittwerorum was published by Neville Marchant and Greg Keighery in 1980 in the journal Nuytsia.

[3] This darwinia is currently only known from eight populations in the lower part of the Stirling Range in the Esperance Plains and Jarrah Forest biogeographic regions, where it grows in open mallee over scrub.
