Winterborne Zelston is a village and civil parish in north Dorset, England. It is situated in a winterbourne valley on the A31 road south of Blandford Forum and north-west of Poole. The parish had a population of 141 in 2001. In 2013 the estimated population of the civil parish was 90.
The first name of "Winterborne" comes from the River Winterborne, which flows from west to east through the village. The river only flows overground during the winter, hence the name. To the west is Winterborne Tomson and to the north-east is Almer. The river flows through both these villages as well.

Dorset Research Tips
One of the many maps available on the website A Vision of Britain through Time is one from the Ordnance Survey Series of 1900 illustrating the parish boundaries of Dorset at the turn of the 20th century. This map blows up to show all the parishes and many of the small villages and hamlets. The internal boundaries on this map are the rural districts which are indicated in the "See Also" box for the place concerned (unless it is an urban parish).
