Agelanthus rondensis is a species of hemiparasitic plant in the family Loranthaceae. It is endemic to Tanzania.
This species has been found only on the Rondo plateau in Tanzania where the threat is from conversion of habitat for agriculture. There is a continuing decline in the extent and quality of habitat. This species has not been seen since its discovery in 1903 in what is a well-surveyed region. Thus, it is possibly extinct.
