IUCr congresses

The triennial congresses of the IUCr are the major international scientific meetings for crystallographers world wide. Each congress includes one or more sessions of the General Assembly which approves the policies of the Union.

The next Congress will be the 27th and will be held in Calgary, Canada, 11-18 August 2026.


It is the policy of the IUCr that strong emphasis should be given to provide a programme that is balanced with respect to gender and nationality.
