Pinchbeck is a village and civil parish in the  South Holland district of Lincolnshire, England. It is situated north from the centre of Spalding. The name Pinchbeck is derived from either the Old English pinc+bece (Minnow Stream) or pinca+bece (Finch Ridge). The village took its name from that of a family long associated with the area, one member of which was Christopher Pinchbeck, a watchmaker responsible for the invention of the Pinchbeck alloy which was formerly used for imitating gold in cheap jewellery.
