The International Workshop on Algebraic Topology (IWoAT) is a series of conferences and summer schools centered around algebraic topology.

It was initiated at the Southern University of Science and Technology in 2018, on the occasion of a joint meeting between the Chinese and American Mathematical Societies. Prior to Covid, in the summer of 2019, the 5-day summer school and 3-day conference at the Shanghai Center for Mathematical Sciences attracted more than 130 participants from around the world. During Covid, IWoAT continued with summer schools online or in a hybrid format, on the topics of equivariant homotopy theory and higher algebra. IWoAT saw its fifth year in 2023 and returned in person, with a week-long conference in July and a summer school in August.

IWoAT has grown along with the strengthening and expanding connections within the greater community of algebraic topology and related fields.
