The Delhi University Students Union, generally abbreviated DUSU, is the umbrella student organisation at the University of Delhi.

The elections to Delhi University Students Union, formerly indirect through the electoral votes of college councillors, are now held by direct voting in the autumn term by the students of the University and constituent colleges. The elections are usually held in August -September of each year.

Former office-bearers of the Union have frequently gone on to influential careers in national politics. This was particularly true in the years of the Emergency.

The current leadership of DUSU is held by the Congress Party-affiliated National Students Union of India.
