Sri Rudram (Sanskrit: श्री रुद्रम्), is a stotra or homage hymn to Rudra (an epithet of Shiva). Shri Rudram is also known as Sri Rudraprasna, Śatarudrīya, and Rudradhyaya. The text is important in Saivism where Shiva is viewed as supreme. The hymn is an early example of enumerating the names of a deity, and is particularly important in Tamil worship of Shiva.
The text is also famous for its mention of the Shaivite Panchakshara ("five-syllable") mantra (Sanskrit: Namaḥ Śivāya), which appears in the text of the Śatarudrīya in the eighth anuvaka.
The earliest homage hymns to Rudra is the Satarudriya found in the Yajurveda (TS 4.5.1-11, VS 16.1-66). The Sri Rudra litany is based on this Vedic Satarudriya hymn.
