The Stradivari Society is a philanthropic organization based in Chicago, Illinois, best known for its arranging deals between owners of antique string instruments such as those made by luthiers Antonio Stradivari and Giuseppe Guarneri, for use by talented musicians and performers.

Enjoying the experience of lending such beautiful violins to those who could use them to grow and launch their careers, a string of loans followed.

Awardees include Joshua Bell, Gil Shaham, Paul Huang, Yi-Jia Susanne Hou, Leila Josefowicz, Philippe Quint, Sarah Chang, Janine Jansen, Vadim Repin, Kristóf Baráti, Hilary Hahn, Maxim Vengerov, and Paul Coletti, all of whom have enhanced their careers playing violins the Society arranged for them to borrow.

The Society's two dozen patrons are each given tri-annual concerts by their sponsored musician during its three-year period.

Inspection and service is performed exclusively by Bein and Fushi three times yearly, and cannot be done by any other luthier without permission.
