Farleigh Wallop is a small village and civil parish in Hampshire, England, approximately 4.7 miles (7.6 km) south of Basingstoke on the slopes of Farleigh Hill (208 m). The parish includes about 1,725 acres (6.98 km).

Since 1486, Farleigh Wallop has been the home of the Wallop family, including John Wallop, Henry Wallop, and Gerard Wallop, 9th Earl of Portsmouth, whose seat, Farleigh House, is in the village. In the 1930s, Farleigh Wallop was the center of the English Array group.

Farleigh House is a C18 country mansion in  the centre of the village. It is the country seat of the Earl of Portsmouth, and has been in the Wallop family hands since C15. An earlier mansion on the same site burned down in C17 and the present building replaced it. In 2024, it offers a location for corporate events, private events, and is a filming location.

The Church of England parish church is Saint Andrews, which stands alone in a field somewhat away from the present village. It is thought that the homes that once were beside the church were destroyed in the C17 civil war. The church was entirely rebuilt both around 1733 and also around 1871 with the tower dating from 1873 with three bells. The church has memorials to members of the Wallop family.
