It is an Awadhi language text attributed to Tulsidas, and is his best known text apart from the Ramcharitmanas. The word 'chālīsā' is derived from 'chālīs' meaning the number 'forty' in Hindi, denoting the number of verses in the Hanuman Chalisa (excluding the couplets at the beginning and the end).

The Hanuman Chalisa praises the power and other qualities of Hanuman including his strength, courage, wisdom, celibacy (brahmacharya), and devotion to Rama.
