In the Imperial Gazetteer of England and Wales (1870–72) John Marius Wilson described Killerby: KILLERBY, a township in Heighington parish, Durham; 7 miles NW of Darlington.

The first element is the given-name Kilvert and the second is bȳ meaning "farm".

Spellings of the place-name suggest the first element was mistaken for Old French culvert ("freeman").
