Westminster Pier is a pier on the River Thames, in the City of Westminster in London, England. It is operated by Thames Clippers' Uber Boat and is served by various river transport and cruise operators.

The former Westminster Floating Dock has existed on this site since the 1950s, running along the River Thames between Kew and London Dock. The floating dock serves as a landing point for many Royal cruises, including the conclusion of Queen Elizabeth II's Commonwealth tour in May 1954.
On 7 February 1955, night watchmen reported finding a leak in the dock that caused the middle section to sink. Port of London Authority workers spent three hours trying to drain the central pontoon, with the pier half flooded at 10am before sinking completely "when Big Ben got stuck at 12am" . No one was injured in the sinking, and staff had time to evacuate and retrieve important documents. The sinking was widely reported in the press and media of the time, and it was parodied in an episode of The Goon Show a week after the incident.
