Bacon is an English surname originally from Normandy and England. In early sources, it also appears as "Bachun" and "Bacun".
Its etymology is uncertain, with Charnock favoring a derivation from a diminutive of Germanic bach ("little stream, creek")[1][2] and others from an eponymous seigniory in Normandy or from a corruption of Beacon.[1] It is sometimes folk etymologized from bacon.[3]
