Lack's Dock is a boat ramp located on the River Thames in London, used as an entry point to the river. It is notably associated with London Duck Tours, whose amphibious vehicles have been documented entering the Thames at this location.

The site sits in proximity to foreshore construction works along the Albert Embankment, and navigational guidance has identified it as a point requiring attention for river users, particularly regarding the risk of vessels drifting toward submerged or partially submerged structures in the event of engine failure.
