South Station Tower is a skyscraper under construction in Boston, Massachusetts, the high-rise portion of a three-building development.

[8] South Station Tower was planned to break ground in 2008, with completion scheduled to occur in 2010, but the project stalled.

[11] The developer's rights to build on the site were scheduled to expire in April 2017,[12] but the state extended them until the end of the year.

The building was conceived by Tufts president Jean Mayer, who foresaw an "epicenter of high-profile medical research" in downtown Boston.

[16] South Station Tower was originally designed with a height of 759 feet (231 m), which included a decorative spire.

[6] The notice included a timeline calling for construction of the project's first building, the high-rise tower, to begin in 2017.

On March 21, 2024, a steel beam fell from the top of the tower, damaging several windows, before coming to rest on the ninth floor.
