The village name is Anglo Saxon in origin and means home farm by a stream. In the Domesday Book of 1086 it was recorded as Bechentone.
Hall Farm in Beachampton was reputedly the home of Catherine Parr at the time that she was married to King Henvry VIII.
Although parts of the village stand on high ground, most of the village is prone to regular floods as the stream that runs through the village, a tributary for the River Ouse, is fairly low lying.
The family name Beachampton originates in this village, and was first recorded in manorial records in 1175 when Osmer de Beachampton was a tenant here.
The parish church is dedicated to the Assumption of St Mary the Virgin.
