Die Fragmente der griechischen Historiker, commonly abbreviated FGrHist or FGrH (Fragments of the Greek Historians), is a collection by Felix Jacoby of the works of those ancient Greek historians whose works have been lost, but of which we have citations, extracts or summaries. It is mainly founded on Karl Wilhelm Ludwig Müller's previous Fragmenta Historicorum Graecorum (1841–1870).
The work was started in 1923 and continued by him till his death in 1959. The project was divided into five parts, of which only the first three were published. The first included the mythographers and the most ancient historians (authors 1-63); the second, the historians proper (authors 64–261); the third, the autobiographies, local histories and works on foreign countries (authors 262-856). The work thus far comes to fifteen volumes, but the fourth (biography and antiquarian literature) and the fifth part (historical geography) were never done. A pool of editors is currently trying to complete this task (Die Fragmente der griechischen Historiker. Continued). Brill's New Jacoby (BNJ) is published online and provides English translations.
