Trencherfield Mill is a cotton spinning mill standing next to the Leeds and Liverpool Canal in Wigan, Greater Manchester, England. It was built in 1907. It was taken over by the Lancashire Cotton Corporation in the 1930s and passed to Courtaulds in 1964. The mill 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. The mill is now part of the Wigan Pier redevelopment area and is used for other purposes.
