Winterborne Zelston is a village and civil parish in north Dorset, England.

[1] It is situated in a winterbourne valley on the A31 road eight miles (thirteen kilometres) south of Blandford Forum and 10 mi (16 km) northwest of Poole.

[6] The parish church is dedicated to St Mary and is a Grade II listed building, being inscribed in the register on 14 July 1955.

Although the main fabric dates from this rebuild, the building has several older features such as a fourteenth century doorway in the south vestry wall, and some of the windows in the chancel, which are thirteenth century.

The tower has three stages, the parapet being battlemented and there being a gargoyle on the west wall.
