Wish Tree for Washington, DC is a public art work by Yoko Ono.

As a part of her Imagine Peace billboard project,[1] it was installed in the Hirshhorn Museum and Sculpture Garden on April 2, 2007,[2] during the 2007 National Cherry Blossom Festival, as one of ten in the city[3] and is part of the museum's permanent collection.

[4] In 2010, a wish tree was installed at the Museum of Modern Art[5] in New York City.

The work builds on the Japanese tradition of tying prayers to trees.

Returning the paper back to its source evokes an offering.
