Caldecote is a village and former civil parish in the North Hertfordshire District of Hertfordshire, England. It is located around three miles north of Baldock and around a mile and a half east of Stotfold in the neighbouring county of Bedfordshire. The Great North Road passes just to the west of the village.
Caldecot now forms part of the Caldecote and Newnham civil parish, which covers an area of only 325 acres (1.32 km2). The village consists of a cluster of cottages around the redundant Church of St. Mary Magdalene, which dates from the 14th and 15th centuries and is in Perpendicular style.
