William Weeks, was the first church architect of the Church of Jesus Christ of Latter Day Saints, and is best known as the architect of the Nauvoo Temple.

The Nauvoo Temple was the second temple constructed by the Church of Jesus Christ of Latter Day Saints. The church's first temple was completed in Kirtland, Ohio, United States, in 1836. When the main body of the church was forced out of Nauvoo, Illinois, in the winter of 1846, the church attempted to sell the building, finally succeeding in 1848. The building was damaged by arson and a tornado before being demolished.
