A new species of Passiflora from the Brazilian Atlantic rainforest in the state of Sao Paulo is described and illustrated. Passiflora loefgrenii is placed in subgenus Passiflora ''series'' Lobatae. It is vegetatively similar to P. amethystina Mikan and P. eichleriana Masters, the three species occurring sympatrically. Passiflora loefgrenii differs from these species primarily by flower character. At the type locality Passiflora loefgrenii is pollinated by hermit hummingbirds and large bees.
