Maquinchao is a village and municipality in Río Negro Province in Argentina.

It is located in the middle of northern Patagonia, right in the steppe. Consequently, the climate can be quite extreme: temperatures can range from well above 35 °C (95 °F) on the hottest summer days (but with cold, desert nights at around 10 °C or 50 °F) to lows that might reach −35 °C (−31 °F). Usually, summer days average 26 °C (79 °F) and nights 8 °C (46 °F), whereas winter days average 6 °C (42 °F) and nights, −5 °C (23 °F). Snow is common, but since precipitation is generally low, quantities tend to be reduced. The weather is generally windy, especially in the spring.
