Wahlenbergia loddigesii is a herbaceous plant in the family Campanulaceae native to the southern Cape regions of South Africa.

Its calyx lobes are short (1.5-2mm), triangular acute, faintly keeled and slightly revolute along the edges.

The ovary is usually minutely hairy, only half inferior, and basally rounded.

It occurs from Ceres and Worcester in the west, to Bredasdorp in the south, Ladismith, Oudtshoorn and Prince Albert in the north, and eastwards as far as Port Elizabeth and Somerset East.

Wahlenbergia loddigesii is most commonly found in dry, stony areas, on slopes or rocky hills.
