Esparto, halfah grass, or esparto grass is a fiber produced from two species of perennial grasses of north Africa, Spain and Portugal. It is used for crafts, such as cords, basketry, and espadrilles. Stipa tenacissima and Lygeum spartum are the species used to produce esparto.

Stipa tenacissima (Macrochloa tenacissima) produces the better and stronger esparto. It is endemic to the Western Mediterranean (growing in Portugal, Spain, Morocco, Algeria, Tunisia and Libya). The Spanish name for the plant is "atocha"; a pre-Roman word. "Esparto" or σπάρτο in Greek may refer to any woven products of sedge or broom, including cords and ropes. This species grows forming a steppic landscape - esparto grasslands - which covers large parts of Spain and Algeria.
