Zehneria alba is a species of flowering plant in the cucumber and gourd family, Cucurbitaceae.

It is endemic to Christmas Island, an Australian territory in the northeastern Indian Ocean.

The specific epithet is from the Latin albus (white), referring to the colour of the flowers.

The leaves are broadly ovate, cordate at the base, unlobed to shallowly 3-lobed, dentate, acute to acuminate, and 50–80 mm long.

[2] Found only on Christmas Island, the vine grows there both within the rainforest and along its shrubbed edges.
