Oshkosh does not have any commercial air service, but Wittman Regional Airport (KOSH) can support any private aircraft that wish to land. If you plan to fly in here during Airventure, you will find yourself among tens of thousands of other aircraft doing the same thing.

The city is located adjacent to the Town of Oshkosh. Oshkosh was named for Menominee Chief Oshkosh, whose name meant "claw" (cf. Ojibwe oshkanzh, "the claw"). Although the fur trade attracted the first European settlers to the area as early as 1818, it never became a major player in the fur trade. Soon after 1830, much of the trade moved west, as there had been over-trapping in the region. The establishment and growth of the lumber industry in the area spurred development of Oshkosh. Already designated as the county seat, Oshkosh was incorporated as a city in 1853. It had a population of nearly 2,800. The lumber industry became well established as businessmen took advantage of navigable waterways to provide access to both markets and northern pineries. The 1859 arrival of rail transportation expanded the industry's ability to meet the demands of a rapidly growing construction market. At one time, Oshkosh was known as the "Sawdust Capital of the World" due to the number of lumber mills in the city, 11 by 1860.
