Tyrannus is a genus of small passerine birds in the tyrant flycatcher family Tyrannidae that are native to the Americas. The majority are named as kingbirds.

 They prefer semi-open or open areas. These birds wait on an exposed perch and then catch insects in flight. They have long pointed wings and large broad bills. These birds tend to defend their breeding territories aggressively, often chasing away much larger birds. A kingbird was photographed in 2009 defending its young by landing on and sinking its talons into the back of a red-tailed hawk and pecking its skull until the red-tailed hawk gave up and flew away.

Taxonomy: The genus was introduced in 1799 by the French naturalist Bernard Germain de Lacépède with the eastern kingbird (Tyrannus tyrannus) as the type species. The genus name is the Latin word for ´tyrant´ and is motivated by the kingbirds´ abovementioned tendency to aggressively chase away any other birds regardless of their size.
