The Stellafane Observatory is an astronomical observatory in Springfield, Vermont, founded in 1920 by Russell W. Porter. The Pink Clubhouse was built in 1923 at the site by the Springfield Telescope Makers Club. The name Stellafane, suggested by Porter at the club's December 1923 meeting, is derived from the Latin words stella and fanum meaning "Shrine to the Stars",^[1] and originally referred specifically to the clubhouse, but has since come to refer to all of the club's land and buildings on the summit of Breezy Hill, west of downtown Springfield.

The Stellafane Convention, a gathering of amateur telescope makers and amateur astronomers is the longest running astronomical convention in the United States,^[2] having been held nearly every year at the location since 1926. The clubhouse and observatory became listed on the National Register of Historic Places in 1977, and became a National Historic Landmark in 1989, in recognition of the club's pioneering role in the popularization of astronomy and the amateur construction of telescopes.^[3][4]
