Hengshan Road (Chinese: 衡山路; pinyin: Héngshān Lù), formerly Avenue Pétain, is a street in the former French Concession of Shanghai, China. A major thoroughfare that connected the heart of the French Concession with the Catholic district of Zikawei (Xujiahui), the boulevard was for much of the 20th century the centre of Shanghai's premier residential district. Since the 1990s, many of the mansions along the road have been converted into bars, night clubs, and restaurants. From 2016 onward, many of the bars on Hengshan Road have been closed down or moved away to other new and more popular entertainment districts in the city.
