Conicosia is a genus of succulent plants in the ice plant family native to the Cape Provinces of South Africa. They are known commonly as narrow-leafed ice plants. These are relatively short-lived perennials with underground stems and tentacle-shaped, dull-pointed triangular leaves. They bear large tubular flowers often exceeding 10 centimeters in width, with up to 250 fringelike petals arranged in a ring around a center with hundreds of stamens. The fruit is a capsule which opens when it gets wet, slowly releasing the hundreds of tiny seeds as they fall out of its drying flesh.

Two species are accepted.

• Conicosia elongata (Haw.) Schwantes
• Conicosia pugioniformis (L.) N.E.Br.
