Sisyrinchium angustifolium is a flowering, perennial, wetland grass-like plant in the iris family (Iridaceae).

Noted for its violet-blue flowers, narrowleaf blue-eyed grass is found in wet, grassy flatwoods, wet prairies, and fields. It grows nearly throughout the state of Florida (Wunderlin, 2003) and the east coast as far north as Quebec (Kartesz, 1999). Sisyrinchium angustifolium blooms from spring to summer and is equally likely to occur in wetlands or non-wetlands (estimated probability 34%-66%).
