Parque Alejo Barrios, Urban park in Playa Ancha, Valparaíso, Chile.

Parque Alejo Barrios is an urban park in Playa Ancha with multiple soccer fields and open green spaces. The grounds sit between educational and military institutions and provide space for sports and community gatherings throughout the year.

The land belonged to Guillermo González de Hontaneda, who bequeathed it to the State after Minister Diego Portales asked for the plain to be used for military drills. By the early 1830s Portales wrote to Antonio Garfias that civic guards would exercise on the "llanos de Playa Ancha", the area of today's park. In the later 19th century it was called Campo de Marte, site of naval parades and of Fiestas Patrias recreation.

Local soccer clubs have used these fields as their home ground for decades, making sports a central part of daily life here. The park remains a gathering place where neighborhood teams and residents come to play and watch matches.

The park is freely accessible and maintained by the local community, with clear pathways and marked fields throughout the grounds. Visitors should expect activity from sports clubs, especially during weekday evenings and weekends when matches and training sessions occur.

On 21 May 1921 two YMCA basketball teams played a public exhibition game here, and in 1922 the first interclub tournament, the Coliseo Popular, was held. Military parades took place on the park's ellipse until the 1973 coup, after which the flat ground was given over to Fiestas Patrias fondas and ramadas.
