真叶植物（英语：Euphyllophytina）是一个未分级的植物类群，是维管植物的子类群，石松门的姊妹类群。真叶植物包括种子植物和蕨类植物两大类，以及一些灭绝的化石类群。根据多项分子生物学证据，现存的维管植物都可以归为石松、蕨类、种子植物这三个单系群。其它的研究表明，将化石种类列入会得到更为复杂的的谱系图。

Euphyllophytina, the euphyllophytes, is a taxon – sometimes unranked, sometimes placed at the informal rank of subdivision – within the tracheophytes. It is sister to subdivision Lycopodiophyta. Euphyllophytina contains the two groups Spermatophytes (seed plants) and Monilophytes (ferns), as well as a number of extinct fossil taxa. The division of the extant tracheophytes into three monophyletic lineages is supported in multiple molecular studies. Other researchers state that taking fossils into account leads to different conclusions, for example that the ferns are not monophyletic.
