The Welshpool Jetty railway was a 2 ft 6 in (762 mm) narrow gauge branch line in Victoria, Australia. It opened on 26 June 1905, and was operated as a horse-drawn tramway, connecting Welshpool station to Port Welshpool. It had a total length of just over 3 miles (4.8 km) and ran to the fishing jetty. The line closed on 1 January 1941.
The jetty was reconstructed prior to World War II to facilitate the berthing of naval vessels, and is the third-longest wooden jetty still standing in Australia. It reverted to commercial uses after the war, but a fire on the pier in June 2003 resulted in WorkSafe Victoria issuing a closure notice.
There is a local campaign to re-furbish and re-open the jetty for tourism, along with a plan for Victoria's first underwater observatory.
