Goodyera repens, an orchid in the genus Goodyera, is called by the common name creeping lady's-tresses in Anglophone Europe{{BSBI 2007|accessdate=2014-10-17}} and dwarf rattlesnake plantain or lesser rattlesnake plantain in North America.

It is a green underground creeper that sends out occasional skinny stems above the surface. During the summer, these stems bear flowers arranged in a spiral. These flowers twist themselves to face toward the sun.

Goodyera repens is found in isolated spots in the forests and bogs of Europe. It is a rare plant, but it is the most common orchid in Scandinavia.{{fact|date=June 2021}} The species is widespread across much of Europe, Asia and North America including Russia, China, Germany, Poland, the United Kingdom, Canada and the United States, though never very common in any of these places.[http://apps.kew.org/wcsp/namedetail.do?name_id=91902 Kew World Checklist of Selected Plant Families][http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=200028685 Flora of North America, v 26 p 516, Goodyera repens ][http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=200028685 Flora of China v 25 p 48, 小斑叶兰 xiao ban ye lan, Goodyera repens ]

Goodyera repens is a protected species throughout most of its range. It does not survive fire, and does not soon reenter an area after fire or logging. It is generally found only in forests at least 95 years old.{{cite web | url = http://www.fs.fed.us/database/feis/plants/forb/goorep/all.html | author = Williams, T.

Like other orchids, Goodyera repens lives in symbiosis with mycorrhiza, rhizome-dwelling fungus (Ceratobasidium cornigerum or Rhizoctonia goodyearae-repentis). The mycorrhiza help the orchid absorb and assimilate nutrients.

This orchid is pollinated by bumblebees, allowing for its sexual reproduction. It can also reproduce vegetatively. Its seeds are famously minute; only 0.000003 of a gram in weight.{{cite book | last= Kerner von Marilaun | first= Anton | date= 1894 | title= The natural History of Plants - Volume 2 | location= London | publisher= Blackie & Son | page= 851 }}
