All Assam Students' Union or AASU is an Assamese nationalist student's organization in Assam, India. It is best known for leading the six-year Assam Movement against Bengalis of both Indian and Bangladeshi origin living in Assam. The original leadership of the organisation, after the historic Assam Accord of 1985, became part of the newly formed Asom Gana Parishad which formed a state government in Assam.
