Santa Rosa – Artillery Colonel Victor Larrea International Airport (IATA: ETR, ICAO: SERO) is a small international airport located near Santa Rosa in El Oro Province, southern Ecuador. It serves as the primary air access point for the region, which is known for banana and shrimp production. The airport handles limited scheduled domestic traffic and has international designation, though regular international services have historically been minimal. It plays a supporting role in Ecuador's aviation network alongside larger hubs such as Quito and Guayaquil. Named in honor of Artillery Colonel Victor Larrea, the facility reflects Ecuador's practice of naming airports after national military and civic figures. Its relatively modest infrastructure is suited to the traffic volumes of the surrounding provincial area.
