The plumbeous tyrant (Knipolegus cabanisi) is a species of bird in the family Tyrannidae, the tyrant flycatchers.

The genus was later spelled Knipolegus. By the 1980s it was widely treated as a subspecies of Knipolegus signatus, which was called by different authors the Andean tyrant and plumbeous tyrant. Following a 2012 publication, in 2013 the South American Classification Committee of the American Ornithological Society split the two, calling signatus Jelski's black-tyrant and cabanisi the plumbeous tyrant. The IOC, BirdLife International's Handbook of the Birds of the World (HBW), and the Clements taxonomy followed suit beginning in 2014. However, as of early 2025 some confusion remains. The IOC calls cabanisi the plumbeous tyrant. Clements, the SACC, and HBW call it the plumbeous black-tyrant. The four taxonomic systems agree that the plumbeous (black-) tyrant is monotypic. == Description == The plumbeous tyrant is 14.5 to 16.5 cm (5.7 to 6.5 in) long.
