Tomahawk Regional Airport (ICAO: KTKV, FAA LID: TKV) is a city owned public use airport located three nautical miles (6 km) west of the central business district of Tomahawk, a city in Lincoln County, Wisconsin, United States. It is included in the Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2021–2025, in which it is categorized as a local general aviation facility.

Although many U.S. airports use the same three-letter location identifier for the FAA and IATA, this facility is assigned TKV by the FAA but has no designation from the IATA (which assigned TKV to Tatakoto Airport in Tatakoto, Tuamotu, French Polynesia).
