Holladay Park, Urban park in northeast Portland, United States.

Holladay Park is a 4.34-acre public park at Northeast 11th Avenue and Holladay Street in northeast Portland, Oregon. It has a fountain, paved paths, picnic tables, and public art, including Tad Savinar's three-part installation Constellation.

Benjamin Holladay, who sold his stagecoach business to Wells Fargo, founded this park in 1870 as he developed railroad connections to California. The location became part of his broader vision for regional infrastructure and land development.

The park holds Constellation, a public art installation by Portland artist Tad Savinar made of three separate sculptural elements: Flowers from a Neighborhood Garden (subtitled Vase of Flowers), Isolated Molecule for a Good Neighborhood (abridged as Molecule), and Neighborhood Gardiner. The pieces stand apart from one another among the paved paths and lawn, so a visitor passes them at different points while crossing the grounds.

Holladay Park sits at Northeast 11th Avenue and Holladay Street, beside the TriMet MAX light rail line. Paved paths cross the grounds and connect to the surrounding Lloyd District streets, so it works as a short cut between the MAX stop and nearby blocks.

The park's public art is Constellation by Tad Savinar, made of three separate sculptural elements: Flowers from a Neighborhood Garden (subtitled Vase of Flowers), Isolated Molecule for a Good Neighborhood, and Neighborhood Gardiner. The pieces stand apart rather than as a single group, so visitors pass them at different points along the paths and lawn.
