West Nantmeal Township is a township in Chester County, Pennsylvania, United States. The population was 2,170 at the 2010 census. It and East Nantmeal Township were originally part of a single Nantmeal Township, which was divided in 1739.

Nantmeal was named by Welsh immigrants from the village of Nantmel in Radnorshire, now part of Powys. The Welsh name, Nantmel, means 'the valley of Mael', a tenth-century prince. The incorrect belief that it means 'Honey Brook' is based on a confusion between the personal name 'Mael', and the Welsh word 'mêl', 'honey'.
