Narayanopanisad is a part of Taittiriya Aranyaka of Krsna Yajurveda. Though it is not one of the ten principal Upanisads, it has a special significance for the followers of Vaisnava tradition. The Supremacy of Visnu is especially brought out in this Upanisad. Many passages of this Upanisad are quoted in Sri Madhvacharya's works and are commented upon.

Two commentaries are available on this work. Sri Dhirendratirtha of Sri Raghavendra Swamy Matha has commented upon it in a lucid way.
