Delta Municipal Airport (IATA: DTA, ICAO: KDTA, FAA LID: DTA) is three miles (6 km) northeast of Delta, in Millard County, Utah. The National Plan of Integrated Airport Systems for 2011–2015 categorized it as a general aviation airport.

The airport opened in June 1943. The airport's runways were last resurfaced around 1989, and due to a lack of funding were risking shutdown by 1999, but as of 2009 the airport is open.
