For millennia, the land now known as Kansas was inhabited by Native Americans. In 1803, most of modern Kansas was secured by the United States as part of the Louisiana Purchase. In 1854, the Kansas Territory was organized, then in 1861 Kansas became the 34th U.S. state. In 1867, McPherson County was founded.

The first post office in McPherson was established in 1873. McPherson was incorporated as a city in 1874.

As early as 1875, city leaders of Marion held a meeting to consider a branch railroad from Florence. In 1878, Atchison, Topeka and Santa Fe Railway and parties from Marion County and McPherson County chartered the Marion and McPherson Railway Company. In 1879, a branch line was built from Florence to McPherson, in 1880 it was extended to Lyons, in 1881 it was extended to Ellinwood. The line was leased and operated by the Atchison, Topeka and Santa Fe Railway. The line from Florence to Marion, was abandoned in 1968. In 1992, the line from Marion to McPherson was sold to Central Kansas Railway. In 1993, after heavy flood damage, the line from Marion to McPherson was abandoned. The original branch line connected Florence, Marion, Canada, Hillsboro, Lehigh, Canton, Galva, McPherson, Conway, Windom, Little River, Mitchell, Lyons, Chase, Ellinwood.

In 1887, the Chicago, Kansas and Nebraska Railway built a main line from Herington through McPherson to Pratt. In 1888, this line was extended to Liberal. Later, it was extended to Tucumcari, New Mexico and El Paso, Texas. It foreclosed in 1891 and taken over by Chicago, Rock Island and Pacific Railway, which shut down in 1980 and reorganized as Oklahoma, Kansas and Texas Railroad, merged in 1988 with Missouri Pacific Railroad, merged in 1997 with Union Pacific Railroad. Most locals still refer to this railroad as the "Rock Island".

By 1888, the community was at the junction of four railroad lines. Major industries have included a large flour mill, an insurance company headquarters, and an oil refinery.

The National Old Trails Road, also known as the Ocean-to-Ocean Highway, was established in 1912, and was routed through Windom, Conway and McPherson.
