The
Hanuman Chalisa is a Hindu devotional hymn (
stotra) addressed to Lord Hanuman. It has been authored by 16th-century poet Tulsidas in the Awadhi language, and is his best known text apart from the
Ramcharitmanas. The word "chālīsā" is derived from "chālīs", which means the number forty in Hindi, as the
Hanuman Chalisa has 40 verses. A rendition of Hanuman Chalisa sung by Gulshan Kumar and Hariharan has received more than 1.2 billion views on YouTube, as of September 2020, becoming the first devotional song in the platform to achieve this feat.
