The Brazilian funnel-eared bat (Natalus macrourus) is a bat species found in eastern Brazil and Paraguay. It roosts in caves, which makes it vulnerable to disturbance of these scarce sites, and in particular, to extermination campaigns against cave-roosting bats carried out in Brazil to combat rabies.

It was formerly considered a subspecies of N. stramineus.{{MSW3 Chiroptera | id = 13801546 | page = 431}}
