Termas de Río Hondo International Airport (Spanish: Aeropuerto Internacional de Termas de Río Hondo) (IATA: RHD, ICAO: SANR) is an airport serving the city of Termas de Río Hondo in Santiago del Estero Province, Argentina.

The airport was inaugurated on 24 July 2012 by President Cristina Fernández de Kirchner;[6] one month later the first flight from Buenos Aires landed at the airport.

[7] Up to the late-1970s, there was an airport here, but it was closed, as both Santiago del Estero, 60 kilometres (37 mi) away from Termas de Río Hondo, and San Miguel de Tucumán, 90 kilometres (56 mi) away, had airports with paved runways.

The airport is beside the Río Hondo Reservoir (es), 6 kilometres (4 mi) west of the city.

The Termas de Río Hondo VOR-DME (Ident: TRH) is located on the field.
