Renhold is a village and civil parish located on the River Ouse, in the hundred of Barford, in the county of Bedfordshire, England. The parish church is situated some 4 miles (6.5 km) east-north-east of Bedford town centre. Bedfordshire County Council estimated the population of Renhold to be 1,800 in 2005, and forecast an increase to 2,320 by 2010.

The parish is made up of several hamlets ("Ends" in local parlance) including Salph End, Church End, Lane End, Top End, Workhouse End, and Water End. In the 2000s, two new housing estates were constructed on the southern boundary of Renhold parish. The Spires and Cranbourne Gardens estates have been established off Norse Road in Bedford, with vehicular access from the Goldington area of the town. The new estates remain part Renhold village for electoral purposes.

The parish is home to Renhold Chapel, All Saints Church at Church End, and the ruins of Renhold Castle. Renhold Castle also known as Howbury, earthwork at Water End Farm, was a medieval castle located in the village.

Renhold Castle was a timber motte-and-bailey castle, encased by a moat. It was located 4 miles east of Bedford Castle and a mile south of Great Barford Castle. Only earthworks remain at the site, which is a Scheduled Monument protected by law.

There is a country house called Howbury Hall in the southern part of the parish. It was rebuilt in 1849, and remains a private home.
