Leasingham is the name of a hamlet on the southern edge of the Clare Valley, in the Mid North of South Australia.

The Riesling Trail is on the western fringe of the township, following the former railway route between Auburn and Clare.

Surveys soon followed, the township being named after the village and civil parish of Leasingham in Lincolnshire, England and the site was once owned by E. Campbell, who held approximately 120 hectares (60 acres) of freehold land, which he sold in 1853.

[2] By 1866 Leasingham had about 130 residents and, although ribbon development occurred around the Main North Road crossroad, it never prospered into a town.

Additionally, being centrally located in quite a picturesque district, it caters for tourism and has a restaurant, caravan park, bed and breakfast accommodation and a number of tasting/cellar door sales operations of local wineries.
