The A151 road is relatively minor part of the British road system. It lies entirely in the county of Lincolnshire, England. Its western end lies at coordinates 52°48.1892′N 0°36.5179′W / 52.8031533°N 0.6086317°W / 52.8031533; -0.6086317 (A151 road, western end) otherwise, grid reference SK938238¹. This article attempts to deal with its several aspects by treating some separately, before integrating them with the others into an overall picture, sequentially from its western end.

In Britain, roads of greater and medium importance are numbered according to a system in which the smaller number of digits indicates a more major route. The motorways are prefixed by M and the principal other roads by the letter A. The roads A1 to A6 radiate from London with A1 as the axial route of the country, running between London and Edinburgh. Roads with numbers beginning with 1 lie to the east of the A1, clockwise when viewed on a map. The details are explained under Great Britain road numbering scheme.
