Parc 55 San Francisco - a Hilton Hotel is a 350 ft (107 m) skyscraper hotel located in Tenderloin, San Francisco, California.

Renaissance Hotels had separated from Ramada in 1989 and been purchased by Marriott in 1997.

In April 2010, the hotel joined Wyndham Hotels and was renamed Parc 55 Wyndham San Francisco - Union Square.

[2] In 2023, Park Hotels & Resorts (an investment trust spun off from Hilton Worldwide in 2017) surrendered Parc 55 and the nearby Hilton San Francisco Union Square to its lender JPMorgan Chase, citing San Francisco's "record high office vacancy; concerns over street conditions; lower return to office than peer cities; and a weaker than expected citywide convention calendar.

"[9] In December 2023, the two hotels were placed into court-appointed receivership, under the control of Hotel Value Asset Enhancement for Wilmington Trust, the entity representing the mortgage lenders.
