Archichrysotus is an extinct genus of flies in the family Dolichopodidae. The generic name is a combination of the Greek prefix archi- ("the first") and the generic name Chrysotus.[1] The genus is known from Upper Cretaceous amber from the Taymyr Peninsula in Russia, New Jersey in the United States and Cedar Lake in Manitoba, Canada.[1][2]

The genus contains four species:

†Archichrysotus hennigi Negrobov, 1978[1] – Taymyr amber, Coniacian/Santonian
†Archichrysotus incompletus Grimaldi & Cumming, 1999[2] – New Jersey amber, Turonian
†Archichrysotus manitobus Grimaldi & Cumming, 1999[2] – Canadian amber, Campanian
†Archichrysotus minor Negrobov, 1978[1] – Taymyr amber, Coniacian/Santonian
