Erie Municipal Airport

Erie Municipal Airport is an airport in Weld County, Colorado, United States. It is owned by the Town of Erie and located three nautical miles (6 km) south of its central business district. This airport was included in the National Plan of Integrated Airport Systems for 2011–2015, which categorized it as a general aviation facility. It was formerly a private airport called Tri-County Airport.

The airport is at the southwestern corner of Weld County, bordering Boulder County to the west and the City and County of Broomfield to the south. This particular part of Broomfield was in Adams County prior to the creation of Broomfield County in 2001. The airport is on the north side of State Highway 7 (Baseline Road) about 4 mi west of I-25. Adjacent to the airport is the Erie Airpark subdivision, a residential area designed for private-plane commuters.

Although many U.S. airports use the same three-letter location identifier for the FAA and IATA, this airport is assigned EIK by the FAA but has no designation from the IATA (which assigned EIK to Yeysk, Russia).
