Gas Company Tower is a 52-story, 749 ft (228.3 m) class-A office skyscraper on Bunker Hill in downtown Los Angeles, California.

Located on the north side of Fifth Street between Grand Avenue and Olive Street, across from the Biltmore Hotel, the building serves as the headquarters for the Southern California Gas Company, which vacated its previous offices on Eighth- and Flower-streets in 1991, and is home to the Los Angeles offices of law firm Arent Fox.

This giant accounting firm moved from nearby Two California Plaza, where it had been since 2000.

[10][11] The County of Los Angeles notified the court-appointed representative of their interest in acquiring the building in mid-2024.
