Passiflora telesiphe is a species of flowering plant in the family Passifloraceae. It is endemic to Ecuador.

This is a vine with slender branches. The three-lobed leaves are up to 8 by 11 centimeters. The upper surface of the leaf is dark green, sometimes mottled with white, and the underside is purple. The flowers are solitary or paired with purple-tinged white petals. The filaments are white or purplish and are up to 2.6 centimeters long. The fruit has not been observed. This species is a member of the subgenus Decaloba.

This plant was first formally described in 1998, when it was discovered in Ecuador five years earlier during an observation of local butterflies by naturalists. A male telesiphe longwing (Heliconius telesiphe) was noted hovering about a plant, and the eggs and pupa of the species were found on it. The new plant was then named after the butterfly.

So far this plant is known only from Zamora-Chinchipe Province. It is found in low Andean forest habitat at elevations of 1,700m.
