Pseudoraphis is a genus of Asian and Australian plants in the grass family, commonly known as mudgrasses.

They grow in open, wet habitat, such as marshes. Some are aquatic, floating plants. A defining characteristic is a long, stiff bristle extending from the tip of each branch of the inflorescence. Pseudoraphis is closely related to the genus Chamaeraphis.
