English: habitational name chiefly from Hesleden in Halton Gill (Yorkshire), though Monk Hesleden (Durham), Haselden (Sussex), Haslingden (Lancashire), and Hazledon Farm (Wiltshire) are alternative possibilities. The Sussex placename derives from Old English hæsel ‘hazel’ + denn ‘pasture’, while the Lancashire placename derives from Old English hæslen ‘growing with hazels’ + denu ‘valley’. The other placenames derive from Old English hæsel + denu. There has been some confusion with Hazelton .
