One Rincon Hill is an upscale residential complex on the apex of Rincon Hill in San Francisco, California, United States. The complex, designed by Solomon, Cordwell, Buenz and Associates and developed by Urban West Associates, consists of two skyscrapers that share a common townhouse podium. It is part of the San Francisco skyline and is visible from several parts of the Bay Area.

The taller tower, One Rincon Hill South Tower, was completed in 2008 and stands 60 stories and 641 feet (195 m) tall.[A][B] The shorter tower, marketed as Tower Two at One Rincon Hill, was completed in 2014 and reaches a height of 541 feet (165 m) with 50 stories.[A] The South Tower contains high-speed elevators with special features for moving residents effectively, and a large water tank designed to help the skyscraper withstand strong winds and earthquakes. Both skyscrapers and the townhomes contain a total of 709 residential units.

The building site, located right next to the western approach of the San Francisco–Oakland Bay Bridge, formerly contained a clock tower. The clock tower was demolished shortly after the city approved the One Rincon Hill project. Construction of the townhomes and the South Tower lasted from 2005 to 2008, but was stopped for brief periods of time due to seismic concerns and a construction accident. As the South Tower neared completion, it generated controversy concerning view encroachment, high pricing, and architectural style.
