The Platte River () is a major river in the State of Nebraska. It is about 310 mi (500 km) long; measured to its farthest source via its tributary, the North Platte River, it flows for over 1,050 miles (1,690 km). The Platte River is a tributary of the Missouri River, which itself is a tributary of the Mississippi River which flows to the Gulf of Mexico. The Platte over most of its length is a broad, shallow, meandering stream with a sandy bottom and many islands—a braided stream. The Platte is one of the most significant tributary systems in the watershed of the Missouri, draining a large portion of the central Great Plains in Nebraska and the eastern Rocky Mountains in Colorado and Wyoming. The river valley played an important role in the westward expansion of the United States, providing the route for several major emigrant trails, including the Oregon, California, Mormon and Bozeman trails. The first Europeans to see the Platte were French explorers and fur trappers about 1714; they first called it the Nebraskier (Nebraska), a transliteration of the name given by the Otoe people, meaning "flat water". This expression is very close to the French words "rivière plate" ("flat river"), the probable origin of the name Platte River.

The Moses Merrill Mission, also known as the Oto Mission, was located about eight miles west of Bellevue, Nebraska. It was built and occupied by Moses and Eliza Wilcox Merrill, the first missionaries resident in Nebraska. The first building was part of facilities built in 1835 when the United States Government removed the Otoe about eight miles southwest of Bellevue. Merrill's goal was to convert the local Otoe tribe to Christianity; he had learned the language and translated the Bible and some hymns into Otoe. The first log cabin had to be replaced after it burned, but by 1835 they had built a combined school/church building. After Merrill died in 1840 from tuberculosis, the Otoe left the mission and moved their village. His wife Eliza Merrill returned to the East with their son. Settlers used the cabin into the 1860s. As of 2005, the only remainders of the second and larger mission building are its original chimney and the cottonwood trees planted by Eliza Merrill. As of July 2016, the last remaining cottonwood tree was torn down. The site was added to the National Register of Historic Places in 1972. The state has placed a highway historical marker near the former site of the Oto Mission.
