The National Deaf Federation Nepal (NDFN; Nepali: राष्ट्रिय बहिरा महासंघ(ne)) is a non-governmental organization established and run as the umbrella organization for Nepal's various district and local deaf associations. Previously it was known as the National Federation of the Deaf and Hearing Impaired (NFDH). It is a member of the World Federation of the Deaf (WFD) and works as an advocate for deaf rights, as well as running a number of programs throughout the country to improve the lives of Nepal's deaf population.
