Seamer is a village and civil parish in the Hambleton district of North Yorkshire, England, near the border with the Borough of Stockton-on-Tees and 3 miles (5 km) northwest of Stokesley.

Its name is first attested in the Domesday Book of 1086 as Semer(s), with later medieval attestations including Samara. The first element is Old English sǣ ‘lake'; the spelling of the second element suggests variation between Old English mere ‘sea’, Old English mersc ‘marsh’, and Old Norse marr ‘lake, sea, pool’. The dominant meaning of the name therefore seems to have been ‘lake by the sea’. (information courtesy of wikipedia http://en.wikipedia.org/wiki/Seamer,_Hambleton )
