Vishnu Sahasranamam is a devotional song based on the Hindu god Vishnu. It is written in the language of the Vaishnavites and has been composed in the style of the Mahabharata.

The song is based on the idea that there are 1000 names of Vishnu and that he has a thousand powers. The text of the song eulogizes Vishnu's divine attributes and powers. The Vishnu Sahasranamam as found in the Anushasana Parva of the Mahabharata is the most popular version of the 1000 names of Vishnu. Other versions exist in the Padma Purana, Skanda Purana and Garuda Purana.

Each name eulogizes one of his divine attributes. The names are divided into three groups: those that eulogize Vishnu's divine attributes, those that describe his extraordinary powers and those that describe his divine nature.

Each name has a reference to one of Vishnu's attributes.
