Cold Ashby is a village and civil parish in West Northamptonshire in England.

[3] Cold Ashby is surrounded by rolling farmland, and has a notable golf club.

Lying on the 200 metres (656 ft) contour line Cold Ashby is said to be the highest village in Northamptonshire.

The British Ordnance Survey's first trig point, the triangular post used by surveyors, was erected on 18 April 1936 near Cold Ashby.

More than 11,000 of the posts were erected across Britain to enable surveyors to create maps accurate to within metres by measuring angles and using trigonometry to calculate distances between the pillars.
