Nepal National Dalit Social Welfare Organization (NNDSWO) is a pioneer organization in combating "caste-based discrimination and untouchability’’ and promoting equality and dignity of Dalit in Nepal. NNDSWO, established in 1982, is a first registered non-government organisation by Dalit for Dalit rights.
NNDSWO is the legitimization of the social movement against caste based discrimination and untouchability started in 1950s by small groups of Dalit activists in different corners of the country to voice against untouchability. The leaders of the time realising the importance of a registered organisation at national level to unite the movement established Nepal National Social Welfare Organisation, later renamed as NNDSWO. The registration of NNDSWO is itself a milestone in the history of the Dalit movement in Nepal. It became a national platform for Dalit activists working in different corners of the country establishing its district chapters in more than 50 districts in the time of registration. In the same spirit it has strengthened its local initiatives building linkages with regional and international human rights advocacy.
