The Prahran and Malvern Tramways Trust (PMTT) was a former tram operator in Melbourne, Australia. The trust was formed in 1907, with its first line operating in 1910. Its functions were taken over by the Melbourne & Metropolitan Tramways Board in 1920.
The PMTT was formed under the Prahran & Malvern Tramways Trust Act 1907 to construct and operate electric trams in the municipalities of Prahran and Malvern. The original members of the trust were Alexander Cameron (Chairman), W. O. Strangward (Secretary), H.S. Dix (Manager and Engineer), S. Bangs, William Knox MLC, Walter Lewis and Thomas Luxton.
Noyes Brothers were selected as the primary contractors for the work. The first rail was laid along High Street on 20 October 1909. Malvern tram depot opened on 30 May 1910 as were the first lines: along High Street from Charles Street, Prahran to Tooronga Road and the other along Glenferrie and Wattletree Roads from High Street to Burke Road.
In 1910, the PMTT was reconstituted to include representatives of the cities of St Kilda and Caulfield. The Trust consisted of five members, one each from the four constituent councils and the Chairman. The first tram service began along High Street on 30 May 1910 with a 6¾ mile track. On 11 July 1911, the Trust was authorized to construct a tramway along Dandenong Road from Glenferrie Road to Chapel Street, Windsor. The route was extended to Caulfield and St Kilda in 1911, and to the CBD in 1912. The extension of the electric tram service along Glen Huntly Road, Elsternwick, took place in 1914.
