Iona is a city in Bonneville County, Idaho, United States. It is part of the Idaho Falls, Idaho Metropolitan Statistical Area. The population was 1,803 at the 2010 census.
Iona was homesteaded by Mormon pioneers in 1883. Sagebrush, as tall as a man sitting on a horse, covered the now famous potato fields. The short growing season made it difficult to grow crops and the early settlers were discouraged and many wanted to go back south to Utah. However, when Mormon apostle Wilford Woodruff spoke to a small congregation in the Iona area on June 17, 1884, he said:
The Spirit of the Lord rests mightily upon me and I feel to bless you in the name of Jesus Christ. I promise you that the climate will be moderated for your good. I can see these great sagebrush prairies, as far as the eye can reach, turned into fertile fields. I bless the land that it shall yield forth in its strength.
