CIRGET is an inter-university research centre based at the Université du Québec à Montréal. The Centre brings together mathematicians working in differential geometry, topology, geometric group theory and mathematical physics. It is one of the CRM's (Centre de recherches mathématiques) nine laboratories.

Every year CIRGET organizes several weekly research seminars and workshops.

- geometric group theory
- low-dimensional topology and geometry
- differential geometry
- symplectic geometry and topology
- geometric methods in partial differential equations
- partial differential equations on manifolds
- gauge theory
- mathematical physics (in particular integrable systems and quantum groups)
- algebraic geometry
- algebraic topology
