King's Inch and the much smaller Sand Inch were islands lying in the estuarine waters of the River Clyde close to Renfrew in Renfrewshire, Scotland. Due to dredging and a change of the course of the main current of the River Clyde, silting, etc. it has become part of the southern, Renfrewshire side, of the river bank and is now built over. The name lives on in a street name, etc. and King's Inch railway station once served Renfrew from 1903 to 1926 on the Glasgow and Renfrew District Railway.
