The Empidoidea are a large monophyletic superfamily of true flies, the sister taxon to the Muscomorpha (= " Cyclorrhapha"). These two groups are sometimes united in the unranked taxon Eremoneura. There are some 10,000 known species in the Empidoidea.

The majority of these insects are predatory, often with large compound eyes (sometimes covering almost the entire surface of the head), and tend to be associated with moist, temperate habitats. Many have a well-developed anal lobe in the wings, and/or a small but distinct anal cell.
