The Serpentine is a lake in Hyde Park, London.

It was formed in 1730 when Queen Caroline, wife of George II, ordered the damming of the River Westbourne which at that time formed eleven natural ponds in Hyde Park. It gets its name from its supposedly snake-like, curving shape.

It provides a haven for wildlife including ducks, geese and swans.

Rowing boats are available for hire.

The Serpentine Art Gallery is nearby in Kensington Gardens.

In 2002, the lake hosted the World Rowing Sprints where several international crews raced over 500 m.
