General Eugenio Alejandrino Garay, colloquially known as Garay, is a district in the Guairá Department of Paraguay. It is located approximately 216 kilometres (134 mi) from Asunción, the capital of Paraguay.

It originally belonged to the Caazapá Department but was transferred to Guairá due to its large area. It was established as a municipality by Law No. 260 on June 23, 1955.

The district is accessible via Route PY08 and is situated south of the city of Villarrica, passing through the city of Ñumí. Within Garay's area lies Cerro Tres Kandú, which at 842 metres (2,762 ft) above sea level is the highest point in Paraguay. Its inhabitants mainly engage in livestock activities and the district also has plywood factories.

Its name honors Eugenio Garay, a Paraguayan military figure during the Chaco War, known for being the oldest officer in the army (at 60 years old) and for his major victory at the Battle of Yrendagüé. There, he led a daring mission of 1,400 men who walked 70 kilometres (43 mi) over three days to capture important water wells, resulting in about 6,000 casualties for the Bolivian army.

Its original name in Guarani was Chararã, meaning "Noisy."
