Lomas de Padierna National Park, National park in La Magdalena Contreras, Mexico City, Mexico.

This protected area covers 34.35 hectares on Cerro del Judío hill, featuring elevations between 2,380 and 2,700 meters above sea level with diverse volcanic terrain and native vegetation.

The park was established on April 22, 1938, following the historic Battle of Padierna fought on August 19, 1847, during the Mexican-American War at this strategic location.

The site serves as an important center for environmental education and historical commemoration, hosting programs that teach visitors about local biodiversity and Mexico's military heritage.

Access is from the Anillo Periférico where it continues as Avenida San Jerónimo toward San Bernabé. The terrain runs from 2,380 to 2,700 meters, with a temperate rainy climate averaging 16.6 °C; the wet season lasts from May to November and peaks in June, July and August. Hailstorms occur about three times a year, and winter days can drop to −5 °C.

The park's name honours the Battle of Padierna, fought at dawn on 19 August 1847 and also called the Battle of Contreras. A simple monument was raised on the hilltop after the fighting, and it was repaired when the protected area was reorganised in 1938.
