The First Presidency of The Church of Jesus Christ of Latter-day Saints has announced the site for the Caldwell Idaho Temple, setting the planned house of worship on a 19.2-acre tract at the southwest corner of W Orchard Ave. and S. Florida Ave. in Canyon County, Idaho. Plans call for an 82,000-square-foot, multistory temple that will include a meetinghouse and an accompanying ancillary building.

The Caldwell temple was announced by President Russell M. Nelson in April 2025, and it now joins a broader wave of temple milestones that also includes projects in Mexico and Brazil. In the same roundup, the San Luis Potosí Mexico Temple is scheduled to begin with a media day on Monday, September 21, 2026, ahead of public tours from Thursday, September 24, through Saturday, October 10, excluding Sundays and Saturday, October 3, and a dedication set for Sunday, November 1, 2026, at 10 a.m.

At the same time, the Santos Brazil Temple is slated for a groundbreaking on Saturday, August 1, 2026, with Elder Ronald M. Barcellos presiding. The Caldwell announcement fits into a pattern that has made Idaho one of the Church’s fastest-growing temple regions, while Mexico and Brazil continue to add to already extensive temple networks in countries with large Latter-day Saint populations.

Idaho is home to more than 480,000 Latter-day Saints meeting in around 1,300 congregations, and the state already has 10 additional temples announced, under construction or in operation. Mexico has more than 1.5 million Latter-day Saints in around 1,800 congregations and now counts 27 temples in operation, under construction or announced. Brazil also has more than 1.5 million members and more than 2,000 congregations, underscoring how temple growth is being concentrated in places where the Church says its membership is deep and established.

Nelson has linked that growth to worship and spiritual formation, saying in a temple context that “Positive spiritual momentum increases as we worship in the temple and grow in our understanding of the magnificent breadth and depth of the blessings we receive there.” He has also said that regular worship in the house of the Lord increases virtue, charity and confidence before the Lord. For church members in Caldwell, the next concrete step is not the announcement itself but the building of a temple that will anchor a growing Latter-day Saint presence in Canyon County.
