Śālikanātha was a Mīmāṃsā philosopher (Pūrva Mīmāṃsā) of roughly 900 AD, a follower of Prabhākara (late 7th century) and an opponent of the Bhāṭṭa school started by Kumārila Bhaṭṭa in the 7th century. Śālikanātha is believed to have written the Prakaraṇapañcikā, which is one of the very few texts available to us to study the Prābhākara school of Pūrva Mīmāṃsā.
