Marchantiales is an order of thallose liverworts that includes species like Lunularia cruciata, a common and often troubleseome weed in moist, temperate gardens and greenhouses.

As in other lower plants, the gametophyte generation is dominant, with the sporophyte existing as a short-lived part of the life cycle, dependent upon the gametophyte.

The genus Marchantia is often used to typify the order, although the species in other orders are more numerous.
