Dubois Municipal Airport (ICAO: KDUB, FAA LID: DUB, formerly U25) is a town-owned public-use airport located three nautical miles (6 km) northwest of the central business district of Dubois, a town in Fremont County, Wyoming, United States. It is included in the National Plan of Integrated Airport Systems for 2011–2015, which categorized it as a general aviation airport.

Although most U.S. airports use the same three-letter location identifier for the FAA and IATA, this airport is assigned DUB by the FAA, but has no designation from the IATA (which assigned DUB to Dublin Airport in Dublin, Ireland).
