Hymenachne is a genus of widespread wetlands plants in the grass family. They may be known commonly as marsh grasses. They are distributed in tropical and subtropical regions of Asia, the Americas, and the Pacific Islands. A species from the Americas, H. amplexicaulis, is well known in other parts of the world as an introduced and invasive species.

Hymenachne is similar to genus Sacciolepis. Both were formerly considered part of Panicum.Hymenachne amplexicaulis

Hymenachne aquatic plants frequently found in marshes and other wet habitats. Their stems are spongy with aerenchyma tissue. The longest stems can reach 4 meters. They are perennial, sometimes with rhizomes. The leaves are linear or lance-shaped. The inflorescence is usually a cylindrical, spike-shaped panicle, rarely with branches.
