The Alhóndiga de Granaditas (public granary) is an old grain storage building in Guanajuato City, Mexico. This historic building was created to replace an old granary near the city's river. The name translates roughly from both Arabic and Spanish as grain market or warehouse. Its construction lasted from 1798 to 1809, by orders of Juan Antonio de Riaño y Bárcena, a Spaniard who was the quartermaster of the city during the Viceroyalty of New Spain. The building received World Heritage listing as part of the Historic Town of Guanajuato in 1988.
