Otterbourne is a village in Hampshire, England. It is located approximately four miles (6 km) south of Winchester and eight miles (13 km) north of Southampton. In October 2002, its population was approximately 1,520, and there were 602 dwellings.
There are three public houses in the village: the White Horse Inn, the Otter, and the Old Forge. There is also a school, a post office and village shop. Before the 21st century, the post office and village shop were located opposite Cranbourne Drive at the bottom of Otterbourne Hill. However, at the end of the 1990s, the car garage at the centre of the village was rebuilt to include a petrol station and convenience store. Shortly after the opening of the convenience store, the village shop closed; the store then expanded to include a post office, taking over all previous functions of the old village shop. Until late 2007 the convenience store was running under a SPAR franchise. It has now been taken over and is owned by Budgens.
