Caldecote is a hamlet in Newport Pagnell parish in the County of Milton Keynes. Until administrative boundary changes in 1995 it was in Buckinghamshire.

The place name is fairly common in England, and is Old English meaning "cold cottage". This refers to a resting place for travellers or other strangers on the road. In this case the road in question is the ancient Watling Street that passes straight through the hamlet.

The place name was once used elsewhere in Buckinghamshire in the ancient village adjacent to Bedgrove, and is in use today as the name of an estate in Milton Keynes.
