One Beacon Street is a modern skyscraper in the Government Center neighborhood of Boston, Massachusetts.

Built in 1972 and refurbished in 1991, it is Boston's 20th-tallest building, standing 505 feet (154 m) tall, and housing 37 floors.

Its position near the top of Beacon Hill gives the building a commanding presence, though it is located away from many other Boston skyscrapers.

With its broadcast mast included, One Beacon Street is the 4th-tallest building in Boston (when measuring to pinnacle height), rising 623 feet (190 m).

In July 2014 MetLife and Norges Bank Investment Management announced that they paid approximately $561 million for the One Beacon Street office building.
