Citigroup Center, 48-floor skyscraper in Bunker Hill, Los Angeles, United States

FourFortyFour South Flower is a 627 ft (191 m), 48-story skyscraper at 444 South Flower Street in the Bunker Hill area of downtown Los Angeles. Its glass curtain wall forms horizontal bands of reflective blue-gray and silver divided into a grid of small rectangular windows, with vertically chamfered corners and a stepped lower setback on the left side. Two small dark rectangular openings sit near the upper right of the front facade.

The site at 5th and Hope streets held the eight-story Sunkist Building, built in 1935 by Walker & Eisen; Sunkist traded the property in 1970 for a larger site on Riverside Drive in Sherman Oaks, and the building was demolished in 1972. The Rockefeller Group developed the present tower, designed by Albert C. Martin & Associates, which opened in 1981 as the Wells Fargo Building and was then the city's fifth-tallest. Beacon Capital Partners bought it for US$170 million in 2003, Coretrust Capital Partners paid $336 million in 2016, and Citigroup left in 2018 for 1 Cal Plaza.

Five artists were commissioned when the tower was built: Mark di Suvero's Shoshone (1981), Michael Heizer's North, East, South, West (1967–1981), Frank Stella's Long Beach XXIII (1982), Robert Rauschenberg's Fargo Podium (1982) and Bruce Nauman's Trench, Shafts, Pit, Tunnel, and Chambers (1982). Augustine Kofie's mural Two-movement was unveiled in spring 2019.

The tower stands at 444 South Flower Street, at the corner of 5th and Flower in Bunker Hill, downtown Los Angeles. The lobby and the commissioned artworks are reached on foot from the surrounding streets; the building is an active office tower, so the public areas are shared with tenants and their staff.

The tower opened in 1981 as the Wells Fargo Building, became Citicorp Center, and took the name FourFortyFour South Flower after Citigroup left for 1 Cal Plaza in 2018. Its lobby holds works by Frank Stella, Robert Rauschenberg and Bruce Nauman, plus Augustine Kofie's 2019 mural "Two-movement".
