Dia Bridgehampton is a museum in Bridgehampton, New York run by the Dia Art Foundation. Opened in 1983 as the Dan Flavin Art Institute, the building was renovated by Dia, under the direction of minimalist sculptor Dan Flavin, as a permanent display of his fluorescent light works in a single-artist museum. The museum also houses a gallery for temporary exhibitions, and a display of historic objects related to the building from before it became a museum.
