Warbstow (Cornish: Lannwarburgh) is a village and civil parish in Cornwall, England, United Kingdom.

Both the neighbouring parish of Treneglos and Warbstow belonged in the 12th century to the Lords of Cardinham who donated them to the priory of Tywardreath.

According to Charles Henderson, writing in 1925, "The presence ... of St Werburga ... is not easily accounted for (though the parish is famous for geese which figure in her legend)".

[3][4] At Lower Youlton farm is a Cornish cross in use as a footbridge; it has undergone much wear from foot passengers and its original location is unknown.

It was once the venue for an annual gathering of Methodists from the circuits of Camelford, Holsworthy (Devon) and Launceston who assembled here on Whit Tuesday for an open air service.
