The tepui wren (Troglodytes rufulus) is a species of bird in the family Troglodytidae.

It is found in Brazil, Guyana, and Venezuela, where it inhabits high tablelands called tepuis.

The adult's crown and upperparts are chestnut brown that is slightly redder on the lower back and rump.

The tepui wren's song is "a series of high, thin whistled twitters" that may run together or be in separate phrases.

[1] Though its population has not been quantified, it is locally common and many of the inhabited tepuis are protected preserves.
