Piney Pinecreek Border Airport (ICAO: K48Y, FAA LID: 48Y, TC LID: K48Y)[1][2] was a public use general aviation airport located 2 nautical miles (3.7 km; 2.3 mi) northwest[1][2] of the central business district of Pinecreek, in Dieter Township, Roseau County, Minnesota, United States, on the Canada–US border.

The airport, located in Manitoba and Minnesota, had both United States and Canada customs services and was attractive to tourists, hunters and fishermen.

[6] An airport for the town of Pinecreek was proposed by resident Eugene Simmons in 1949, to expedite cross-border general aviation traffic.

[7] Citing declining usage and significant impending repair costs, it was announced that the airport was scheduled for permanent closure on December 27, 2024.

[9] Without funding for repairs, officials from both governments elected not to renew the international agreement required to continue airport operations past this date.

Pilots and passengers in Canada needed to walk across Provincial Trunk Route 89 to report to CBSA, while in the US, the border station was located on the airport side of Minnesota State Highway 89.
