The Idaho Falls Idaho Temple (formerly the Idaho Falls Temple) is the tenth constructed and eighth operating temple of The Church of Jesus Christ of Latter-day Saints (LDS Church). Located in the city of Idaho Falls, Idaho it was the first LDS temple built in Idaho, and the first temple built with a modern single-spire design.
The temple in Idaho Falls was announced on March 3, 1937. The building was designed by the church board of temple architects: Edward O. Anderson, Georgious Y. Cannon, Ramm Hansen, John Fetzer, Hyrum Pope, Lorenzo Snow Young. The exterior of the temple was completed in September 1941 and the interior was expected to be completed the following year. However, with World War II shortages, it delayed the completion of the temple for four more years. In spite of delays, LDS Church president George Albert Smith dedicated the Idaho Falls Temple just one month after the war ended, on September 23, 1945. The temple was built on a Template:Convert plot, has 4 ordinance rooms and 9 sealing rooms, and has a total floor area of Template:Convert.
The name of the temple was changed from the Idaho Falls Temple to the Idaho Falls Idaho Temple in 1999 when the church introduced standardized naming conventions for temples worldwide.
In March 2015, the temple closed for renovations that were expected to last 18 months. The renovations took nearly two years and following their completion, a public open house was held from April 22 through May 20, 2017, excluding Sundays. The temple was rededicated by Henry B. Eyring on June 4, 2017.
