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

It is indigenous to arid areas near Klaarstroom in the Western Cape, South Africa.

This species can be distinguished by its bright, white margins on its slender, upcurved leaves.

The leaves grow in pairs, that each appear in a decussate arrangement (each leaf-pair at right angles to the previous one, rather than all in the same two distichous rows).

It most resembles its close relative, Glottiphyllum difforme, that grows to the east.
