Singleborough is a hamlet in the parish of Great Horwood (where the 2011 Census population was included), in Buckinghamshire, England. It is located about a mile from the main village.
The hamlet name is Anglo Saxon in origin, and means 'gravel hill'.
It appears spelt as Synkelburgh, in 1440, on a plea roll of the Court of Common Pleas, where a resident Thomas May, with others, was accused of trespassing on John Carter's land in Great Horwood & assaulting him.
