Iatan is a village in Platte County, Missouri within the United States. The population was 69 at the 2010 census. It is within the Kansas City metropolitan area.

The community is said to derive its name from Iatan, a chief of the Otoe tribe who supposedly derived his name from battles with the Comanche who were sometimes also referred to as Iatan. The town site was platted in 1842. A post office called Iatan was established in 1855, and remained in operation until 1964.

Iatan, first settled by John Dougherty in 1837, was one of the first communities to be established after the Platte Purchase allowed white settlement on former Native American land (which was proclaimed in February 1837). It was initially an important trading port on the Missouri River but was soon overtaken by Weston, Missouri five miles (8 km) to the south and St. Joseph, Missouri 20 miles (32 km) to the north.

The community's name is applied to the Iatan 1 and Iatan 2 coal-fired power stations for Kansas City Power & Light which is the largest coal-fired generating plant in Missouri.

The Iatan 2 plant opened in 2010 and can generate 850 Megawatts with a capacity to burn 494 tons of coal per hour. The new plant has a lower 60-foot (18 m) high mechanical cooling tower.
