Boissonneaua is a small genus of hummingbirds in the family Trochilidae. They are found in humid Andean forests from western Venezuela to southern Peru. They have a straight black bill, contrasting outer rectrices, and a distinctive habit of quickly lifting both wings up shortly after landing, thereby revealing their rufous underwing coverts.
