The Leeuwenhoek Lecture is a prize lecture of the Royal Society to recognize achievement in microbiology.

[1] The prize was originally given in 1950 and awarded annually, but from 2006 to 2018 was given triennially.

The prize is named after the Dutch microscopist Antonie van Leeuwenhoek and was instituted in 1948 from a bequest from George Gabb.

A gift of £2000 is associated with the lecture.
