藓纲（學名：Bryopsida）在生物分类学上是苔藓植物门（Bryophyta）中的一个纲。它是苔藓植物门中最大的一纲，包含95%的全部的藓纲物种。它约有15,000种。中国约有500余种。泥炭藓亚纲（Sphagnopsida）仅有一目一科，泥炭藓目（Sphagnales），泥炭藓科（Sphagnaceae），泥炭藓属（Sphagnum），约300余种，多分布于北半球温带地区。中国的主要分布于东北、西北和西南高寒沼泽地区，常见的有泥炭藓。黑藓亚纲（Andreaeopsida）仅有一目一科，黑藓目（Andreaeales），黑藓科（Andreaeaceae），两个属，中国仅有黑藓属（Andreaea），疣黑藓分布于陕西、安徽和福建。真藓亚纲（Bryopsida）最大，有12—19目，真藓目（Bryales），是苔藓植物中科、属、种最多的一个目，遍布全世界。中国常见的有葫芦藓。

The Bryopsida constitute the largest class of mosses, containing 95% of all moss species. It consists of approximately 11,500 species, common throughout the whole world.

The group is distinguished by having spore capsules with teeth that are arthrodontous; the teeth are separate from each other and jointed at the base where they attach to the opening of the capsule. Consequently, mosses in the Class Bryopsida are commonly known as the "joint-toothed" or "arthrodontous" mosses. These teeth are exposed when the covering operculum falls off. In other groups of mosses, the capsule is either nematodontous with an attached operculum, or else splits open without operculum or teeth.
