According to Wikipedia:
Om Namah Shivaya is one of the most popular Hindu mantras and the most important mantra in Shaivism. Namah Shivaya means "O salutations to the auspicious one!", or “adoration to Lord Shiva". It is called Siva Panchakshara, or Shiva Panchakshara or simply Panchakshara meaning the "five-syllable" mantra (viz., excluding the Om) and is dedicated to Shiva.
