Khao Yai Art Forest (; ) is an open-air museum in the Khao Yai area of Nakhon Ratchasima province, near Khao Yai National Park.
The 161 acres of land for the museum was purchased in 2022 by Marisa Chearavanont, a Korean-born philanthropist. The museum opened on 6 February 2025.
The Forest features artworks made using local materials that are integrated into the natural landscape, including a fog sculpture by Fujiko Nakaya and a Maman spider sculpture by Louise Bourgeois, along with a rice field. The Forest also features a bar designed by Elmgreen & Dragset.
