Wahlenbergia tenella (known as the "Fine Capebell") is a herbaceous plant in the family Campanulaceae native to the southern Cape regions of South Africa.

The base of the filaments is truncate-to-obovate (sometimes even appearing to be 3-lobed), and is covered in thick, short cilia.

Its calyx lobes are relatively short (2-3mm), acute, involute and, as with the leaves, sometimes with a few minute marginal teeth near the base.

It occurs from Cape Town in the west, to Bredasdorp in the south, Ladismith in the north, and eastwards as far as Port Elizabeth and Queenstown in the Eastern Cape Province.

It is most commonly found in lower altitude sandy substrates, especially on coastal plains but also sometimes inland.
