Ishana (Sanskrit: ईशान, IAST: Īśāna), is a Hindu god and the dikpala of the northeast direction.

[19][20] The Purana states that Ishana bestows knowledge and riches on those with intelligence, while curbing evil-doers.

[21] Ishana is declared to be the form of Shiva presiding over the ear, speech, sound and ether as well as the "individual soul, the enjoyer of Prakriti".

[27] The Purana mentions Ishana as one of the deities present at Daksha's sacrifice who was attacked by Virabhadra.

He is described as wearing tiger's skin, adorned with a crescent crown on his head, possessing three eyes and holding a trident, patissa (sword) and club.

[31] Each of these aspects are glorified in their own mantra in the Pañchabrahma Mantrani present in the Taittiriya Aranyaka (TA 10.17-21).

According to the Secret Storehouse Records (祕藏記) she is flesh white in color and wields a spear.
