The city was named when the valley in which it stands was called Middle Valley. The first settlers came in 1868 (The Keithley and Towell families) and in 1876 a post office and school were begun. In 1884 the Middle Valley Ditch was undertaken: in 1885 the first store was built, and in 1898 the P&IN Rail Road came through. From 1870 to 1900 stock raising was the chief industry, but today Midvale serves a diversified farming area. Midvale is the hometown of former U.S. Senator Larry Craig.
