The buff-breasted tody-tyrant (Hemitriccus mirandae) is a species of bird in the family Tyrannidae, the tyrant flycatchers.

[4][5] The buff-breasted tody-tyrant has a disjunct distribution in northeastern Brazil, intermittently in the states of Ceará, Paraíba, Pernambuco, and Alagoas.

It mostly forages from the forest's understory to its middle levels, often in dense vine tangles, between about 2 and 5 m (7 and 16 ft) above the ground.

It mostly takes prey using short upward sallies from a perch to grab it from the underside of leaves.

The buff-breasted tody-tyrant's song is a "short series of 7-8 sharp, well-accentuated notes, slightly accelerating and ascending".

It has a disjunct distribution and its estimated population of between 1500 and 7000 mature individuals is believed to be decreasing.
