Shri Hanuman Chalisa is a Hindu devotional hymn addressed to Hanuman. It is traditionally believed to have 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.
