Kimbolton is a town and civil parish in the Huntingdonshire district of Cambridgeshire, England. Kimbolton is about 9 miles (14 km) west of Huntingdon and 14 miles (23 km) north of Bedford.

Kimbolton was also situated within historic Huntingdonshire when it was a county of England. The parish includes the hamlet of Stonely. Catherine of Aragon, after her divorce from Henry VIII, died at Kimbolton Castle in 1536.

Limited archaeological finds in the vicinity of the airfield suggest that there may have been a small Roman settlement. The name Kimbolton, however, is Anglo-Saxon meaning "Cenebald's Ton" (or estate).

Kimbolton, and the lands of its soke, comprised the only estate of King Harold in Huntingdonshire. It is believed that Harold had a hunting lodge nearby. The town was listed as Chenebaltone and Kenebaltone in the Domesday Book of 1086 in the Hundred of Leightonstone in Huntingdonshire. The survey records that there were 20 ploughlands at Kimbolton in 1086 and, in addition to the arable land, there were 70 acres (28 hectares) of meadows, 3,784 acres (1,531 hectares) of woodland and a water mill. There was already a church and a priest at Kimbolton.

The parish church of St Andrew is Grade I listed. Historic England. "Church of St Andrew, Kimbolton (Grade I) (1210885)". National Heritage List for England. Many members of the Montagu family (Earls and Dukes of Manchester of Kimbolton) are buried at St Andrew's. Several Montagu monuments still exist in the South Chapel, while the Montagu vault (extended in 1853) is located beneath the North Chapel.

The main road through Kimbolton bends through four tight right angles in quick succession. Originally, the road travelled directly through the outskirts of the town, nearer to the River Kym to the north.

The parish also includes the hamlet of Stonely, site of the former Augustinian Stoneley Priory.

In the centre of the town is Kimbolton Castle which now forms the main building of Kimbolton School (an independent day and boarding secondary school), but its predecessor on the same site was once home and prison to Catherine of Aragon after her divorce from Henry VIII. Catherine died at Kimbolton Castle in 1536 and was transported from there to Peterborough Cathedral to be buried.
