Walsden (/ˈwɒlzdən/; WOLZ-dən) is a large village in the civil parish of Todmorden in the Metropolitan Borough of Calderdale, West Yorkshire, England.

Multiple small craters can still be picked out on both hillsides, one of which contains the Summit Tunnel trans-Pennine railway line, which may have been an alternative target for a raid primarily aimed at the Manchester area; its easterly Yorkshire end is less than ¼ mile away.

The road was quickly repaired, the canal was shored up with earth from the former floodplain of Walsden Water (which is why the pitches are above the natural ground level) and the whole bombing incident was hushed up.

Warland, Bellhome, Bottomley, Lanebottom, Deanroyd, Bottoms, Allescholes, Birkswood, Ramsden, Henshaw, Hollins and Copprashouse are all part of what is now generally referred to as Walsden.

Foreign refers to the Celtic Britons who lived in West Yorkshire at the time of the Anglo Saxon Petty Kingdoms.
