We establish the supercongruences for the fourteen
rigid hypergeometric Calabi--Yau threefolds defined
over the rational numbers. The existence of such supercongruences
was conjectured (based on numerical evidence) by
F. Rodriguez-Villegas in 2003.

This is joint work with Ling Long, Fang-Ting Tu
and Wadim Zudilin.
