There are two interpretations of the place name Croxdale both based on the personal Old English name Croc:

  • Croc’s dal; dal meaning dale or valley so literally Croc’s valley.
  • Croc’s tail of land; tail meaning a piece or slip of irregularly bounded land, jutting out from a larger piece.

Croxdale has been associated with the landowning Salvin family since early times and developed into the present community as a result of the sinking of Croxdale Colliery around 1845.
