Trencherfield Mill is a cotton spinning mill standing on the Leeds and Liverpool Canal, Wigan, Greater Manchester. It was built in 1907. It was taken over by the Lancashire Cotton Corporation in the 1930s and passed to Courtaulds in 1964. It was driven by a 2,500 hp triple-expansion four-cylinder engine built by J & E Wood of Bolton in 1907. The two halves of the engine were called Rina and Helen. They drove a 26-foot flywheel with 54 ropes at 68 rpm. The engine was stopped in 1968. It is now part of the Wigan Pier redevelopment area.
