Eastern Idaho, Geographic region in Idaho, United States.
Eastern Idaho stretches from the Snake River Plain toward the Wyoming border, covering land shaped by mountains, valleys, and farming areas across thirteen counties. Two cities, Idaho Falls and Pocatello, serve as the main population centers and economic hubs for the region.
The region was home to Shoshone and Bannock peoples before Mormon settlers arrived in the 1860s and established agricultural communities. This early settlement period shaped the region's economy and culture, with farming becoming the foundation for decades of growth.
The region carries strong Mormon heritage from its 19th-century settlement, shaping community values and social gatherings that remain central to local life. This influence is visible in the architecture, religious institutions, and the close-knit feeling of towns throughout the area.
The region is best explored by car since towns and attractions are spread across larger distances. Both main cities offer services like hotels, restaurants, and shops, making them good bases for visiting nearby areas.
The Idaho National Laboratory, situated between Idaho Falls and Arco, stands as one of the nation's leading nuclear research centers and shapes the region's scientific identity. Its presence has influenced local employment and attracted specialized professionals to the area.
