The white-tailed nuthatch (Sitta himalayensis) is a species of bird in the family Sittidae.

It is found in Bhutan, India, Laos, Myanmar, Nepal, Tibet and Thailand.

It may be identified by the buff underside, smaller beak than in the Kashmir nuthatch (S. cashmirensis).

The white on the upper tail coverts is difficult to see in the field.

It has a small bill and rufous-orange underparts with unmarked bright rufous undertail-coverts.
