Tirunilanakka Nayanar, also known Tiruneelanakka, Nilanakkar and Nilanakkan, was a Nayanar saint, venerated in the Hindu sect of Shaivism. He is generally counted as the twenty-eighth in the list of 63 Nayanars. He is described as a contemporary of Sambandar, one of the most prominent Nayanars.

The Nayanars were a group of 63 Tamil Hindu saints living during the 6th to 8th centuries CE who were devoted to the Hindu god Shiva. Along with the Alvars, their contemporaries who were devoted to Vishnu, they influenced the Bhakti movement in early medieval South India. The names of the Nayanars were first compiled by Sundarar. The list was expanded by Nambiyandar Nambi during his compilation of material by the poets for the Tirumurai collection, and would include Sundarar himself and Sundarar's parents.
