Milecastle 67 (Stainton) is a conjectured milecastle of the Roman Hadrian's Wall. The site of the milecastle has been calculated from measurement to known milecastle sites, but no remains providing proof of its existence have been identified, though Roman coins were found in 1861, during the digging of the adjacent railway cutting.
