The Carisbrook to Horsham Pipeline (also known as the GPV Pipeline) is a transmission pipeline located in western Victoria. The pipeline is owned by Gas Pipelines Victoria (GPV).

The pipeline is 183 km in length. It provides high-pressure natural gas from the Carisbrook metering station and supplied via the Victorian DTS to AusNet Services, who in turn supply end-use customers in Avoca, Ararat, Stawell and Horsham.
