The Worshipful Company of Clockmakers was established under a Royal Charter granted by King Charles I in 1631. It ranks sixty-first among the livery companies of the City of London, and comes under the jurisdiction of the Privy Council. The company established a library and its museum in 1813, which is the oldest specific collection of clocks and watches worldwide. This is administered by the company's affiliated charity, the Clockmakers' Charity, and is presently housed on the second floor of London's Science Museum. The modern aims of the company and its museum are charitable and educational, in particular to promote and preserve clockmaking and watchmaking, which as of 2019 were added to the HCA Red List of Endangered Crafts.

A livery company is a type of guild or professional association that originated in medieval times in London, England. Livery companies comprise London's ancient and modern trade associations and guilds, almost all of which are styled the "Worshipful Company of" their respective craft, trade or profession. There are 111 livery companies in total. They play a significant part in the life of the City, not least by providing charitable-giving and networking opportunities. Liverymen retain voting rights for the senior civic offices, such as the Lord Mayor, Sheriffs and Common Council of the City Corporation, London's ancient municipal authority with extensive local government powers.
