Ogbourne St. George is a pleasant small village in the valley of the River Og in the Marlborough Downs south of Swindon. The village is centred on the High Street where there is an interesting variety of houses and cottages ranging from period thatched and timber framed to modern buildings. The village is bypassed by the A346.

The name of the village comes from the diminutive River Og, really no more than a stream, which rises near the nearby hamlet of Draycot Foliat and flows south to meet the River Kennet. The name of the river is derived from "Ogbourne" which itself came from the original Occa's Stream, which as its name implies is an intermittent stream, often dry in the summer months

The parish church, St. George's, may be Norman. The three-bay arcade of the south aisle is Early English Gothic and the arcade of the north aisle is slightly later. The church's windows and bell tower are Perpendicular Gothic additions from later in the Middle Ages.

The church stands next to the manor house, a 16th century brick building that stands on the site of an earlier priory.

About a mile to the south-west is the village of Ogbourne St. Andrew and just beyond that the hamlet of Ogbourne Maizey, both of which are on the River Og.

Ogbourne St. George is on the A346 Swindon to Marlborough road, about 3 miles north of Marlborough.
