Strange-tailed tyrants belong to the bird family 'Tyrannidae', which is the largest bird family on earth with over 400 species. In the 1730s, the English naturalist Mark Catesby described the eastern kingbird ('Tyrannus tyrannus') as a tyrant. Inspired by Catesby, Carl Linnaeus, the Swedish biologist that developed the system of taxonomy used today, gave the eastern kingbird the name 'Lanius tyrannus' in 1758.

In 1799, the genus name was changed to 'Tyrannus' by the French naturalist Bernard Germain de Lacépède, who named the genus after the eastern kingbird's species name. Then, in 1825, the Irish zoologist Nicholas Aylward Vigors named the eastern kingbird's family 'Tyrannidae' after its genus 'Tyrannus'. Now, members of 'Tyrannidae' are referred as 'tyrants' because of their family name, which is how the strange-tailed tyrant got its name. Its defining feature is its large and unusual tail consisting of feathers longer than the rest of its body.

It is found in northeastern Argentina, Paraguay, Uruguay, and three small separated localities in southern Brazil. Its natural habitat is subtropical, tropical, dry lowland, or grassland.
