PMI Victorian History Library Inc.

PMI Victorian History Library Inc. (Formerly Prahran Mechanics' Institute) is a community-owned subscription library situated at 39 St Edmonds Road, Prahran, Victoria, Australia. The library focuses on collecting resources about every locality in Victoria and every aspect of the history of the state. The library was previously situated in High Street, Prahran from 1915 to 2014 and Chapel Street, Prahran from 1854 to 1915. It is one of the oldest surviving Mechanics' Institutes in Victoria and one of only six still operating as a lending library. It was the only mechanics' institute in Victoria still governed by its own Act of Parliament. But in 2022 it incorporated as the PMI Victorian History Library Inc. under the Associations Incorporation Reform Act (2012).

The Institute spawned the Prahran Technical School, which went on to be one of Australia's leading art schools.
