Peperomia serpens, the vining peperomia, is a species of flowering plant in the genus Peperomia and family Piperaceae, native to the New World Tropics. The plant is perennial.

The name Peperomia serpens has in the past also been used to describe Peperomia dimota and Peperomia subrotundifolia. In addition the terms Peperomia serpens and Peperomia scandens are sometimes falsely used for Peperomia nitida, perhaps because both are similar vining plants. The Royal Horticultural Society has bestowed the Award of Garden Merit to "Peperomia scandens" as a houseplant, however it is not clear whether this means Peperomia serpens or Peperomia nitida.
