Nampa () is the largest city in Canyon County, Idaho, United States. Its population was 100,200 at the time of the 2020 Census. It is Idaho's third-most populous city. Nampa is about west of Boise along Interstate 84, and six miles (10 km) west of Meridian. It is the second principal city of the Boise metropolitan area. The name "Nampa" may have come from a Shoshoni word meaning either moccasin or footprint. According to toponymist William O. Bright the name comes from the Shoshoni word /nampai/, meaning "foot". History Nampa had its beginnings in the early 1880s when the Oregon Short Line Railroad built a line from Granger, Wyoming, to Huntington, Oregon, which passed through Nampa. In Nampa there is a history museum marking the significance of the railroad company. More railroad lines sprang up running through Nampa, making it a very important railroad town. Alexander and Hannah Duffes established one of the town's first homesteads, eventually forming the Nampa Land and Improvement Company with the help of their friend and co-founder, James McGee. In spite of the name, many of the first settlers referred to the town as "New Jerusalem" because of the strong religious focus of its citizens. After only a year the town had grown from 15 homes to 50. As new amenities were added to the town, Nampa continued its growth and was incorporated in 1891. Unlike most towns in that historic era with streets running true north and south, Nampa's historic roads run perpendicular to the railroad tracks that travel northwest to southeast through the town. Thus, the northside is really the northeast side of the tracks, and the southside is really the southwest side of the railroad tracks. Founder Alexander Duffes laid out Nampa's streets this way to prevent an accident like one that occurred earlier in a town he had platted near Toronto, Ontario, Canada. In that town, a woman and her two children were killed by a train when they started across the railroad tracks in a buggy and the wheel got stuck. As the Oregon Short Line railroad originally bypassed Boise, Nampa has the fanciest of many railroad depots built in the area. The first elementary school was built in the 1890s. Lakeview School was on a hill on 6th Street and 12th Avenue North, with a view of Lake Ethel. Just after the school's centennial celebration, it was condemned as
