The black-throated munia or Jerdon's mannikin (Lonchura kelaarti) is a small passerine bird.

The nest is a large domed grass structure in a tree or creepers on a house into which 3-8 white eggs are laid in India, and usually five in Sri Lanka.

The adult of the southwest Indian population, L. k. jerdoni, has a stubby grey bill, dark brown upperparts with pale shaft streaks; a blackish face and bib; and pinkish brown underparts with scaly marking towards the vent.

The nominate form L. k. kelaarti of Sri Lanka has scaly patterning on the underparts and vent with the pale almost whitish shaft streaks contrasting on the darker back.

The sexes are similar in all populations, but immatures lack the darker face and have more uniform underparts.
