多尔索杜罗区（Dorsoduro）是威尼斯的六个区之一。

多尔索杜罗区包括威尼斯最高的土地，以及朱代卡岛和萨卡菲索拉岛（Isola Sacca Fisola）。它的名字来源于意大利语“硬脊”，由于其相对较高的，稳定的土地。

Dorsoduro is one of the six sestieri of Venice, in northern Italy.

Dorsoduro includes the highest land areas of the city and also Giudecca island and Isola Sacca Fisola. Its name derives from the Italian for "hard ridge", due to its comparatively high, stable land.
