The Long-tailed Wren-babbler or Naga Wren-babbler (Spelaeornis chocolatinus) is a bird species in the family Timaliidae.

Several former subspecies of this bird have now been recognized as good species. They are: Pale-throated Wren-babbler (S. kinneari), Chin Hills Wren-babbler (S. oatesi) and Grey-bellied Wren-babbler (S. reptatus).

The natural habitat of the Long-tailed Wren-babbler are subtropical or tropical moist montane forests. Following the splitting of the newly-recognized species, the populations remaining in S. chocolatinus are small enough to warrant uplisting to Near Threatened status, from the previous IUCN assessment of Least Concern.
