**真双子叶植物**（学名：eudicots）是指花粉具有三孔（具三叉沟型花粉粒）的植物类群，属于被子植物的演化支之一。该植物学术语由进化植物学家詹姆斯·A·道尔（James A. Doyle）和古植物学家卡罗尔·L·霍顿（Carol L. Hotton）在1991年所倡议，其划分出了被子植物门中的“非木兰类双子叶植物”，包括了绝大部分双子叶植物纲中的种类，而其他没有包括进去的双子叶植物被称为“类双子叶植物”或**古雙子葉植物**（并系群）。

## 特征

有时也将真双子叶植物分支称为“三孔花粉组”，因为它们的花粉都具有三个或三个以上的孔，这种性质和其他被子植物区别开来，其他被子植物包括单子叶植物纲和比较原始的双子叶植物如木兰目等都的花粉都是无孔或只具有单孔、双孔等。

## 分类

真双子叶植物的分类被APG分类法和APG II分类法采纳，作为一个依照基因亲缘关系分类的类群，包括了传统分类法中双子叶植物纲的绝大部分种类。

真双子叶植物的核心是蔷薇类和菊类两大部分，他们的核心分别为“真”蔷薇类和“真”菊类。
