The Ribenboim Prize, named in honour of Paulo Ribenboim, is awarded by the Canadian Number Theory Association for distinguished research in number theory by a mathematician who is Canadian or has close connections to Canadian mathematics. Normally, the winner will have received their Ph.D. in the last 12 years. The winner is expected to give a plenary talk at the award ceremony.
Due to the COVID-19 pandemic, the 2020, 2022, and 2024 Ribenboim Prizes were all awarded in 2024.
