Sexhow is a hamlet and civil parish in Hambleton district of North Yorkshire, England. The name of the hamlet derives from Old Norse of either sexhou or sekkshaughr, which means the hill of Sekk, a personal name. The population taken at the 2011 Census was less than 100, so details of the population are included on the civil parish of Potto. However, in 2015, North Yorkshire County Council estimated the population to be 20. It is on the River Leven and 5 miles (8 km) west of Stokesley.
