Grand Canal Dock is an area near the city centre of Dublin, in the easternmost part of Dublin 2 and the westernmost part of Ringsend in Dublin 4, surrounding the Grand Canal Docks, an enclosed harbour or docking area between the River Liffey and the Grand Canal. Since 2000 the area has undergone significant redevelopment as part of the Dublin Docklands area redevelopment project.

The Grand Canal Docks first opened in 1796. At the time they were the world's largest docks. They fell into decline within just a few decades, due mostly to disuse with the arrival of the railways. The landscape was overwhelmed by Dublin Gas Company's mountains of black coal, along with chemical factories, tar pits, bottle factories and iron foundries. However, bakers and millers maintained business along the southern edge of the inner basin.

Over the last ten years a number of significant developments have happened since involving the construction of millions worth of real estate, the arrival of several thousand new residents, and the establishment of what is now known locally as Silicon Docks.
