Hazelwood (until recently spelt Hazlewood) is a village in Derbyshire at the lower end of the Pennines around five miles north of Derby, England. Ordnance Survey maps in the nineteenth century spelt it Hazzlewood. The population of the civil parish at the 2011 Census was 330. It is located on the western edge of Chevin Hill. Nearby is a place called Firestone where beacon fires were lit to rouse the country when peril of invasion or other dangers were imminent. Firestone is now the site of a reservoir owned by the Severn Trent water board.
