Asparagus setaceus, commonly known as Common Asparagus Fern, Lace Fern, Climbing Asparagus, or Ferny Asparagus, is a climbing plant in the genus Asparagus. Despite its common name, the plant is not a true fern, but has leaves that resemble one.

It is native to Southern Africa, and is grown elsewhere as an ornamental plant. It has become an invasive species in several locations where it has been introduced. Originally described by the German botanist Carl Sigismund Kunth, its specific name is derived from the Latin saeta "hair" or "bristle", hence "hairy". Some authorities use the name A. plumosus (plumosus Latin "plumed", referring to the foliage) as described by Baker in 1875 for this plant, or Protasparagus plumosus (Baker) Oberm.
