Hilton San Diego Bayfront, Modern skyscraper in downtown San Diego, United States

The Hilton San Diego Bayfront is a 30-story, 385-foot tower designed by John Portman & Associates, with a light gray facade of rectangular panes and a darker glass strip on its left side. The word Hilton and a circular logo sit near the top, and the base widens under a flat overhanging roof above a glass-walled ground floor. It stands beside San Diego Bay, next to the Convention Center.

Designed by John Portman & Associates, the hotel was under construction when a natural gas explosion on May 19, 2008, injured 14 workers and damaged four floors. It opened later that year. In 2011 Hilton sold 75% to Sunstone Hotels for $475 million while remaining operator, and a $23 million room renovation followed in 2019.

The hotel's 2019 renovation drew its interior design from San Diego's maritime culture. Its 165,000 square feet of convention space make it the largest meeting and convention hotel in downtown San Diego. A skybridge links the parking garage to a crosswalk toward Petco Park and the Gaslamp Quarter.

The hotel connects directly to the San Diego Convention Center, which helps visitors attending events there. A skybridge links the parking garage to a crosswalk leading to Petco Park and the Gaslamp Quarter. The building has more than 165,000 square feet of meeting space.
