The Immaculate Conception Cathedral (), also known as the Zamora de Hidalgo Cathedral, is a Catholic religious building built in the first half of the 19th century by the famous Celayan architect Eduardo Tresguerras. It is located in the Michoacan city of Zamora de Hidalgo in Mexico.
It was built between 1832 and 1838.
In neoclassical style, it bears some resemblance to the Temple of Carmen in the city of Celaya (also made by Tresguerras).
