Fordingbridge is a town and broader civil parish with a population of 6,200 on the River Avon in the New Forest District of Hampshire, England. It is located near the Dorset and Wiltshire borders and on the edge of the New Forest.

It is 81 miles (130 km) southwest of London, and 10 miles (16 km) south of the city of Salisbury. Fordingbridge is a former market town famed for its seven-arch late medieval bridge, which crosses the River Avon at the centre of the town. The Avon Valley Path passes through the town.

Since 1982 Fordingbridge has been twinned with Vimoutiers in Normandy, France.

Known as "The Northern Gateway" to the New Forest, Fordingbridge is popular with tourists, with various campsites, pubs and restaurants, and other tourist facilities locally. The Fordingbridge Museum, which houses many local and New Forest history exhibits, and the Visitor Information Centre are located within King's Yard, Salisbury Street. The town's High Street is well known for its pubs, cafes and local shops. The town also has its own Cinema, within the buildings of a former pottery.

The village of Breamore is 3 miles north of Fordingbridge and is home to Elizabethan country house, Breamore House.

The Great Bridge, from which the town received its present name, has seven arches and can be seen from the town's large riverside park and recreation ground. The park contains a children's play area, secluded memorial gardens, and large sports playing field. A bronze statue of the painter and former resident Augustus John stands on the banks of the Avon near the Great Bridge.

St. Mary's Church, which has some typical Norman characteristics, is located in the south of the town. The church has a memorial to James Alexander Seton, last British person killed in a duel in England. The town also has a Catholic church in the form of Our Lady of Sorrows and St Philip Benizi. The Building dates from 1874 while the altar dating from 1897 was originally used at Netley Hospital.

Fordingbridge Hospital is a small community hospital built within the grounds of a Victorian workhouse. Most of the older buildings have been redeveloped into private housing, however, the hospital site still houses an inpatient ward, as well as limited outpatients services. Fordingbridge Doctors Surgery is on the same site in Bartons Road. Fordingbridge Hospital was used as a COVID-19 vaccination centre from 2020.

The local comprehensive school is The Burgate School and Sixth Form Centre, in Burgate, a small hamlet to the north of the town.
