The Jacob Spori Building was a historic building located in Rexburg, Idaho listed on the National Register of Historic Places. It was the first building built at the permanent location of Ricks College, a college founded in 1888 by the Church of Jesus Christ of Latter-day Saints.

It was built during 1900 to 1903. Its external walls were faced with ashlar, and were 51 inches (1.3 m) at the foundation, 32 inches (0.81 m) at the first floor windows, 28 inches (0.71 m) at the second floor windows, and 24 inches (0.61 m) at the third floor windows. Lighter colored sandstone was used for string courses encircling the building.

The building was destroyed by a fire in 2000. A new Spori Building was built on the same site and in a similar style.
