Fields Medal

The Fields Medal is a prize awarded to two, three, or four mathematicians under 40 years of age at the International Congress of Mathematicians (ICM) of the International Mathematical Union (IMU), a convention which takes place every four years. The name of the award honors the Canadian mathematician John Charles Fields. Its purpose is to give recognition and support to younger mathematical researchers who have made major contributions to the field of mathematics.

The Fields Medal is regarded as one of the highest honors a mathematician can receive, according to the annual Academic Excellence Survey by ARWU, and has been described as the "Nobel Prize of Mathematics". In another reputation survey conducted by IREG in 2013–2014, the Fields Medal came closely after the Abel Prize as the second most prestigious international award in mathematics.

The medal was first awarded in 1936 to Finnish mathematician Lars Ahlfors and American mathematician Jesse Douglas, and it has been awarded every four years since 1950. In 2014, the Iranian mathematician Maryam Mirzakhani became the first female Fields Medalist. With the exception of two Ph.D. holders in physics (Edward Witten and Martin Hairer), only people with a Ph.D. in mathematics have won the medal. In total, 68 people have been awarded the Fields Medal as of 2026. The most recent group of Fields Medalists received their awards on 23 July 2026, in Philadelphia.

Fields was instrumental in establishing the award, designing the medal himself and funding the monetary component, though he died before it was established and his plan was overseen by John Lighton Synge. The prize includes a monetary award which, since 2006, has been CA$15,000.
