Glottiphyllum oligocarpum is a species of succulent plant, in the family Aizoaceae.

It is indigenous to arid areas of the Little Karoo, in the Western Cape, South Africa.

The stems branch until the plant forms a clump The stalk-less fruits have soft, conical bases, and fall off the plant when they dry, becoming tumble fruits and spreading the seeds.

This species resembles its close relative Glottiphyllum nelii which overlaps it in range, but mostly grows to the north in the Great Karoo.

However G.nelii has shiny leaves, without any pale, waxy covering, and often has translucent lines along its leaf margins.
