Ehrharta is a genus of plants in the grass family.[2][3]

Most of the species are native to Africa, with a few from Southeast Asia and from various islands in the Atlantic, Pacific, and Indian Oceans. The genus is also found in Australia, southern Asia, the Mediterranean, and North America. Several including Ehrharta longiflora, Ehrharta calycina and Ehrharta erecta are considered invasive weeds.[4][5][6][7]

Common names for this genus include veldtgrass.[8][9][10]

This genus was named for the German botanist Jakob Friedrich Ehrhart, 1742-1795.[2][11]
