Upwaltham is a scattered settlement and civil parish in the South Downs, in the District of Chichester of West Sussex, England.

The barns of one of the farmsteads, Upwaltham House Farm, are now a conference and wedding venue.

[2] About 1 mile (1.6 km) south of the church are a few houses at Benges, where the A285 to Chichester leaves the valley.

Compass Bus route 99 between Petworth and Chichester serves Upwaltham six days a week, from Monday to Saturday.

[10] From the Middle Ages onward, Upwaltham was in the hundred of Boxgrove in the Rape of Chichester.

In 1949 two RAF Gloster Meteors crashed in the area, one of them possibly in Upwaltham parish.

Local farmworkers rescued the pilot from the cockpit, but he was badly burned and died two days later in St Richard's Hospital in Chichester.

The weather was worsening, visibility had decreased to 25 yards (23 m), and the crew may not have realised they were no longer over the sea.

The aircraft's port wing hit trees on Upwaltham Hill and was torn off.

[17] On 25 November 1949 two Gloster Meteor Mk IV aircraft of 43 Squadron at RAF Tangmere crashed on the South Downs, killing their pilots.

[19] In 2009 an engraved stone plaque was unveiled in St Mary the Virgin parish church commemorating the 15 airmen killed in the Lancaster and Skytrain crashes.
