Grand Canal Dock (Irish: Duga na Canálach Móire) is a Southside area near the city centre of Dublin, Ireland. It is located on the border of eastern Dublin 2 and the westernmost part of Ringsend in Dublin 4, surrounding the Grand Canal Docks, an enclosed harbour where the Grand Canal comes to the River Liffey. The area has undergone significant redevelopment since 2000, as part of the Dublin Docklands area redevelopment project.

The area has been nicknamed "Silicon Docks" by Google and Facebook (a reference to Silicon Valley) as it has become a popular location for multinational technology firms such as Google, Facebook, Twitter, LinkedIn, and Airbnb. The area has been the subject of debate over the balance of development and gentrification as well as the subject of derision over the clichéd nature of its new nickname.
