The Braconidae are a family of parasitoid wasps. After the Ichneumonidae, braconids make up the second largest family in the order Hymenoptera, with approximately 17,000 recognized species and many thousands more undescribed. One analysis estimated a total between about 30,000 and 50,000, and another provided a narrower estimate between 42,000 and 43,000 species.

Braconidae is currently divided into about 47 subfamilies and over 1000 genera, which include Ademon, Aleiodes, Aphanta, Asobara, Bracon, Cenocoelius, Chaenusa, Chorebidea, Chorebidella, Chorebus, Cotesia, Dacnusa, Kollasmosoma, Microgaster, Opius, Parapanteles, Phaenocarpa, and Psenobolus.

These fall to two major groups, informally called the cyclostomes and noncyclostomes. In cyclostome braconids, the labrum and the lower part of the clypeus are concave with respect to the upper clypeus and the dorsal margin of the mandibles. These groups may be clades that diverged early in the evolution of braconids.

The morphological variation among braconids is notable. They are often black-brown (sometimes with reddish markings), though some species exhibit striking coloration and patterns, being parts of Müllerian mimicry complexes. They have one or no recurrent veins, unlike other members of the other famlily in Ichneumonoidea (Ichneumonidae), which usually have two. Wing venation patterns are also divergent to apparent randomness. The antennae have 16 segments or more; the hind trochanters have two segments.
