Rivero's barn owl (Tyto riveroi) is an extinct species of barn owl that was very large — bigger than any extant barn owl species, and possibly larger than any known owl alive today.

[1] It is thought to have been nearly as large as (but probably not as tall as) another extinct gigantic owl, Ornimegalonyx.

[2] Suárez and Olson demoted T. riveroi as a junior synonym of Tyto pollens in 2015.
