Gopāla-tāpanī Upanishad is an Upanishad, associated with the Atharvaveda. It figures in the Muktika canon of 108 Upanishads.
As with most of the late Upanishads, the Gopāla-tāpanī is said to be attached to the Atharva-veda. In the Muktikā, the distribution of the Upanishads between the Ṛg, Śukla-yajus, Kṛṣṇa-yajus, Sāma and Atharvan is rather complicated. Nevertheless, all four Tāpinī Upanishads (Nṛsiṁha, Rāma, Tripurā and Gopāla) are also listed there as belonging to the Atharvaveda.
