Towersey is a village and civil parish about 1+1⁄2 miles (2.4 km) east of Thame in Oxfordshire.

This refers to a dry area of land in the marshes of the Aylesbury Vale, on the edge of which the village stands.

[4] A manuscript of 1174 records Kingsey also as simply Eya, but thereafter both toponyms gained prefixes to distinguish the two villages.

[7] In 1850–54 the church was restored under the direction of the architect James Cranston, who added the bell tower in its slightly unusual position on the south side of the nave.

[12] Thame was the nearest station until 1933, when the Great Western Railway opened Towersey Halt on the west side of the bridge.

The trackbed has been converted into the Phoenix Trail for cycling, horseriding and walking between Princes Risborough and Thame.
