Harborough Magna is a village and civil parish in the Rugby district, in the county of Warwickshire, England.

Harborough Magna was to be the site of a motorway service station, first planned in 1975, on the M6 (the partially constructed slip roads are visible between the B4112 and Montilo Lane bridges), but the allocated site was too small,[citation needed] and the plans were scrapped in 1980.

[citation needed] Harborough Magna was mentioned in the Domesday Book as Herdeberge.

For many years the main source of employment in the village were sawmills near the canal at Cathiron.

[4][3] Around one mile north-east of the village, within the parish is the St Mary's nursing home for the elderly.
