The name Allerton is of Anglo-Saxon origin, and is a locational name from any of the various places so called. Allerton in Lancashire, Chapel Allerton in the West Riding of Yorkshire, and most of the others in West Yorkshire, are recorded as "Alretune" in the Domesday Book of 1086, and are so called from the Olde English pre 7th Century "alra", genitive plural of "alor", alder, and "tun", enclosure, settlement. Allerton Maulever in West Yorkshire, entered as "Alureton" and "Alvertone" in the Domesday Book, and Chapel Allerton in Somerset ("Alwarditona" in Domesday) have as their component elements the Olde English personal name "Aelfweard", a compound of "aelf", elf, and "weard", guardian", and "tun" (as before).
Mauleverer is a Norman personal nick-name meaning ‘poor harrier (hunter)’ Mauleverer therefore distinguishes the village from Northallerton, Allerton Bywater and Chapel & Moor Allerton in Leeds.
