盾叶茅膏菜（学名：Drosera peltata），又名茅膏菜、盾叶毛毡苔、石龙牙草、石持草，是多年生草本茅膏菜属食虫植物。具有明显的茎，株高10-30厘米，叶为半月形，上面生满能分泌粘液的腺毛。当小虫落上被粘液粘上，叶子卷缩，分泌消化液将虫子消化，是干旱少养分土壤中生长的植物为自己补充营养的一种方式。花白色或淡红色，螺状聚伞花序。

盾叶茅膏菜为攀附性的球根毛毡苔，是分布最广的种类。种加词「peltata」来源于拉丁文「盾形」之意，描述茎上长出的叶片形状。此品种虽然特色鲜明，但又和其他几个相近的种类混在一起，例如在澳洲就有至少4个茅膏菜的型：盾状盾叶茅膏菜（D. peltata subsp. peltata）（自动名）、耳状盾叶茅膏菜（D. peltata subsp. auriculata）、多叶茅膏菜（D. foliosa），又称为盾叶茅膏菜多叶变种（D. peltata var. foliosa）、小型茅膏菜（D. gracilis），又称为盾叶茅膏菜小型变种（D. peltata var. gracilis）。

Drosera peltata, commonly called the shield sundew or pale sundew, is a climbing or scrambling perennial tuberous species in the carnivorous plant genus Drosera. Among the tuberous sundews, D. peltata has the largest distribution, which includes eastern and western Australia, New Zealand, India, and most of Southeast Asia including the Philippines. The specific epithet is Latin for "shield shaped", a reference to the shape of the cauline leaves. It is either a single extremely variable species, or a complex of several closely related species of uncertain taxonomic boundaries. In Australia at least four forms have had or still have specific taxonomic recognition: Drosera peltata subsp. peltata (an autonym), D. peltata subsp. auriculata, D. foliosa (also as D. peltata var. foliosa) and D. gracilis (also as D. peltata var. gracilis).
