Søren Kierkegaards Plads is a harbourside public square on Slotsholmen in central Copenhagen, Denmark. It occupies a strip of waterfront between the Black Diamond, whose main entrance faces the square, and the Frederiksholm Canal. Away from the water, the square is faced by Christian IV's Brewhouse as well as his old arsenal, now housing the Royal Military Museum. The thoroughfare Christians Brygge runs through the square which is connected to the water by "ghats" which also serve as seating for spectators for the occasional performances on a floating stage in the harbour basin.
It was laid out in 1999 in connection with the construction of the adjacent Black Diamond.
