'''''Colubrina pedunculata''''' is a shrub in the family Rhamnaceae. It is endemic to Christmas Island, an Australian territory in the north-eastern Indian Ocean. Its specific epithet comes from the Latin ''pedunculatus'', referring to the long and conspicuous peduncle of the inflorescence.<ref name=fao>Flora of Australia Online.</ref>

==Description== ''Colubrina pedunculata'' is a thorny, sometimes straggling, shrub or small tree. Its thorns are 5–20&nbsp;mm long. Its leaves are alternate, narrowly elliptic, and deciduous after fruiting. It bears many yellow-green flowers, 5–6&nbsp;mm across and clustered. The fruit is about 7&nbsp;mm long.<ref name=fao/>

==Distribution and habitat== Found only on Christmas Island, the plant is common on the northern and north-eastern terraces, in areas of poor, dry soil, among limestone pinnacles and scree, and in cliff edge thickets.<ref name=fao/>

==Relationships== Since it is closely related to the widespread ''C. asiatica'' (L.) Brongn., the fruit of which is used as a fish toxin, and the leaves of which are used medicinally to treat skin diseases, similar chemical or pharmacological properties may be expected in ''C. pedunculata''.<ref name=fao/>
