Rowsham is a hamlet in the parish of Wingrave, in Buckinghamshire, England. It is located to the south of the main village on the main road that links Bierton with Wing.

The hamlet name is Anglo Saxon in origin, and means 'Hrothwulf's home'. In manorial rolls of 1170 it was recorded as Rollesham.

In recent times there has been a campaign among the local residents of Rowsham to have the speed limit through their hamlet reduced from 60 miles per hour to 40 miles per hour. This is on account of the fact that there is a dangerous bend in the road where the hamlet is located, that is a common place for car accidents to occur.
