Westmoreland Park, Urban park in southeast Portland, United States.

Westmoreland Park is a large recreational area in southeast Portland featuring baseball diamonds, tennis courts, basketball facilities, and picnic spaces for public use. The grounds also include a nature-based play area with water features and streams alongside a baseball stadium.

Portland acquired this land in 1936 from a steel manufacturing company that previously operated on the site. The initial facilities were built during the 1930s by workers in a federal employment program.

The park's casting pond hosts the Royal Rosarian Milk Carton Boat Race each summer, a local tradition in which participants build boats from milk cartons. The Uroboros sculpture by Charles Kibby, installed in 1979, stands in the park. Sckavone Field, named in 1955, honors Nick Sckavone, a pharmacist and baseball fan who pushed for the ballfield.

The park is open daily from early morning until midnight and provides parking near the main entrances for visitors. Pathways are well maintained with benches throughout and restroom facilities positioned at convenient locations.

Before the park existed, the site served as an aviation field; in October 1919 it was renamed Broomfield Aviation Field after Hugh Broomfield, a Reed College student and pilot killed in combat during World War I. The 2014 restoration, assisted by the United States Army Corps of Engineers, converted the duck pond into wetlands, and migrating salmon returned to Crystal Springs Creek.
