Rio de Los Angeles State Park, State recreation area in Glassell Park, Los Angeles, US.

Rio de Los Angeles State Park is a 40-acre California State Park on San Fernando Road in Glassell Park, north of downtown Los Angeles, along the Los Angeles River. It holds restored wetlands of native plants, sports fields, a children's playground and a recreation building, and is managed with the City of Los Angeles Department of Parks and Recreation.

The site was once Taylor Yard, a freight facility operated by Union Pacific and Southern Pacific railroads starting in the 1920s. After closing in 1985, the industrial land was transformed into a park with restored natural wetlands.

The park's name comes from the Rio de Los Angeles, the Spanish name for the Los Angeles River it borders. The site is managed jointly by California State Parks and the City of Los Angeles Department of Parks and Recreation, and its sports fields and playground draw local families at weekends.

The park is easy to explore on foot, by bike, or while jogging with several entry points and parking areas available. Bring water and sun protection as the open fields offer limited shade and exposure to direct sunlight can be intense.

In early 2015 conservationists tried to reintroduce native steelhead trout to the Los Angeles River beside the park; nearly all the juvenile fish were eaten by the river's existing fish population, and the attempt failed. The river now holds common carp, largemouth bass and Nile tilapia.
