Dianthus mooiensis (Frilly carnation) is a species of flowering plant in the family Caryophyllaceae.

[1][2] It is indigenous to the highveld terrain in the northern parts of South Africa, being recorded from Gauteng Province, around Pretoria and Heidelberg, and as far west as Potchefstroom in the North West Province.

[3] Dianthus mooiensis is a spreading or tufted herbaceous perennial.

The claw is not exserted though (unlike that of D. zeyheri).

The calyx is 1.5 to 1.75 cm in length, with several bract-pairs at the base.
