Guardia Marina Zañartu Airport ({{langx|es|Aeropuerto Guardia Marina Zañartu}}) {{airport codes|WPU|SCGZ}} is an airport serving the town of Puerto Williams on the north shore of Navarino Island in the Magallanes Region of Chile. The island is at the southern tip of Chile, and is across a narrow strait from Argentina called Beagle Channel. It is the world's southernmost airport with regular scheduled flights.{{Cite web|url=https://www.cnn.com/travel/article/most-extreme-airports-world/index.html|title=The world's most extreme airports|author=Miquel Ros|website=CNN}}

The airport is maintained by the General Directorate of Civil Aviation of Chile (DGAC Chile). The runway is on a small peninsula running parallel to the island's shore, and approaches to either end are partially over the water. There is mountainous terrain to the north and to the south.

Navigation is supported by a VOR-DME on the field.{{Cite web|url=https://ourairports.com/navaids/PWL/Puerto_Williams_VOR-DME_CL/|title=PWL @ OurAirports|website=ourairports.com}}
