Sagittariidae is a family of raptor with one living species—the secretarybird (Sagittarius serpentarius) native to Africa.

German naturalists Otto Finsch and Gustav Hartlaub established the taxon name as a subfamily—Sagittariinae—in 1870. Although their term postdated Gypogeranidae of Vigors (1825) and Serpentariidae of Selys Longchamps (1842), the genus name Sagittarius (described in 1783) had priority over Gypogeranus Illiger, 1811 and Serpentarius Cuvier, 1798.

A genus Pelargopappus is known from Miocene deposits in France. The genus Amanuensis is known from Miocene deposits in Africa.[3][4]
