Kristin Armstrong Municipal Park, Park in Boise, Idaho, United States

Kristin Armstrong Municipal Park is a 28-acre public park along the Boise River in Boise, Idaho. It includes a playground for ages 2 to 12, bocce and tennis courts, picnic shelters with grills, open lawns, and restrooms in a year-round shelter building near the Boise River Greenbelt.

The Boise Commercial Club built the park in 1918 on land leased from the Boise School District, opening it as the Boise Tourist Campground with overnight camping facilities. It closed briefly in 1938 and reopened as a day-use park called Boise Municipal Park. From 1939 to 1963, the southwest portion held Airway Park, later Braves Field, the city's minor league baseball ground; the wooden venue was razed and the site became headquarters of the Idaho Department of Fish and Game. The park was rededicated in 2016 for three-time Olympic gold medalist Kristin Armstrong.

The park's name honors Kristin Armstrong, the Boise cyclist who won three Olympic gold medals in the time trial. The picnic tables and bocce courts are used for casual games and gatherings, but the site's past as Braves Field, the city's minor league baseball park from 1939 to 1963, is not marked. The land later became the headquarters of the Idaho Department of Fish and Game.

The park is open from sunrise to sunset, with designated parking lots nearby, and visitors should leave vehicles only in marked spaces to avoid towing. Weekday mornings and evenings tend to be less busy, and the paved riverfront path offers an easy walk for strollers and wheelchairs.

The park sits directly on the Idaho Birding Trail via the Greenbelt, so a short walk from the picnics can lead to herons, kingfishers, and warblers along the riverbank. Even many regular visitors never notice that the ground under their feet was once a baseball diamond where Boise residents watched early local matchups.
