Leeds City Museum, originally established in 1819, reopened in 2008 in Leeds, West Yorkshire, England. It is housed in the former Mechanics' Institute built by Cuthbert Brodrick, in Cookridge Street. It is one of nine sites in the Leeds Museums & Galleries group.

Mechanics' institutes, also known as mechanics' institutions, sometimes simply known as institutes, and also called schools of arts, were educational establishments originally formed to provide adult education, particularly in technical subjects, to working men in Victorian-era Britain and its colonies. They were often funded by local industrialists on the grounds that they would ultimately benefit from having more knowledgeable and skilled employees. The mechanics' institutes often included libraries for the adult working class, and were said to provide them with an alternative pastime to gambling and drinking in pubs.
