Ingersoll Airport (ICAO: KCTK, FAA LID: CTK) is a public use airport located two nautical miles (2.3 mi, 3.7 km) northwest of the central business district of Canton, a city in Fulton County, Illinois, United States. The airport is owned by the Canton Park District. It is included in the FAA's National Plan of Integrated Airport Systems for 2011–2015, which categorized it as a general aviation facility.

Although many U.S. airports use the same three-letter location identifier for the FAA and IATA, this facility is assigned CTK by the FAA but has no designation from the IATA.

The airport received $360,000 as part of the Rebuild Illinois program to help the airport repair and maintain facilities during the COVID-19 pandemic.
