All Nepal National Independent Students Union (Sixth) (Nepali: अखिल (छैठौं)) was a students organisation in Nepal. It is the students wing of the Communist Party of Nepal (Fourth Convention), later of the Communist Party of Nepal (Unity Centre). In 2002, ANNISU (Sixth) merged with the All Nepal National Independent Students Union (2022) (the students wing of Communist Party of Nepal (Masal), which had split off from ANNISU (Sixth) in 1983) and formed the All Nepal National Independent Students Union (United).[1][2]
