The Hamilton Public Library (HPL) is the public library system of Hamilton, Ontario, Canada.^[1]

HPL services include the Local History and Archives department (formerly called Special Collections), which houses an extensive collection of local history resources and government documents from the City of Hamilton, and the Learning Centre, which provides access to language materials for new Canadians.

Public libraries have operated in Hamilton since the 1830s, although the first branches were privately operated and tended to be ephemeral in nature.

Hamilton and Gore Mechanics' Institute was one of a series of Mechanic's Institutes that were set up around the world after becoming popular in Britain. The Mechanic's Institutes libraries eventually became public libraries when the establishment of free libraries occurred.^[3]

Hamilton city council voted to publicly fund the construction and operation of a library in 1889. This building opened in February 1890. Hamilton was the first city in Canada to erect a new building for the express purpose of housing a library. A HPL branch opened on Hamilton's Barton Street in 1908.^[4] Andrew Carnegie funded a new main library, which opened in 1913. This was in turn replaced by a new, six-storey central library in 1980. Today, only one half of the building houses public collections. Once restricted to the city of Hamilton, the HPL service area was expanded when the outlying townships were amalgamated into the City in 2001. The now-amalgamated City of Dundas had had its own library in operation since 1822.^[4] The outlying rural towns had previously been served by the Wentworth Libraries system. In 2001, the Wentworth and Dundas libraries amalgamated with the HPL into a single system with 22 branches,^[5] 34 bookmobile stops, a virtual online branch and a Visiting Library Service for the homebound.^[4]
