Paris Commune Square (Vietnamese: Công trường Công xã Paris) is a small square located in District 1, downtown Ho Chi Minh City, Vietnam.

It lies between Lê Duẩn Boulevard and Nguyễn Du Street and surrounds the Notre-Dame Cathedral Basilica of Saigon.

The square is surrounded by two remarkable architectural works: Notre-Dame Cathedral and Central Post Office.

As the central post office is nearby, the square is also marked as the city's kilometre zero.

[1] In 1903, the colonial government erected a bronze statue of French Catholic priest Pigneau de Behaine and juvenile Prince Nguyễn Phúc Cảnh[2] in the center of the garden in front of the cathedral, and the square is thus known as place Pigneau de Béhaine.
