Sandy is a town and civil parish in Central Bedfordshire, England. It lies 8 miles (13 km) to the east of Bedford, 18 miles (29 km) to the south west of Cambridge and 43 miles (69 km) north of Central London. It had a population of 12,171 at the 2021 census.

The town takes its name from a low range of sandy hills on the eastern side of the town, which form part of the Bedfordshire Greensand Ridge. The main part of the built-up area lies between the hills to the east and the River Ivel to the west. The A1 road skirts the western edge of the town. Sandy railway station is on the Great Northern route between London and Peterborough, with the railway running along the eastern edge of the built-up area. The parish also includes the hamlet of Beeston, which straddles the A1 to the south-west of the town.

The headquarters of the Royal Society for the Protection of Birds (RSPB) is at The Lodge at Sandy Warren in the hills to the east of the town, where it has been based since 1961.

The Sandy area has a long history of occupation, with evidence found for settlement prior to 250 BC. Sandy was a Roman settlement, when it was probably an important trading centre and staging post. An ancient hill fort, now heavily wooded and traditionally known as Caesar's Camp, although more commonly called "the sand hills" or "the lookout", still overlooks the town.

Sandy is referred to in the Domesday Book of 1086, as Sandeia, a derivation from the Old English Sandieg, meaning a sand-island. At that time it was part of the ancient hundred of Weneslawe and was held by Eudo Fitzhubert, who is likely to have been the tenant. He was probably also known as Eudo Dapifer, who was a high steward for William the Conqueror, and based in Colchester Castle.

There were two mills listed in Sandy in the Domesday Book, which would have been water-powered. One of these mills is likely to have been at Sandy Mill on the River Ivel to the south-west of the town. This was at the end of Mill Lane, adjoining The Riddy, which is now a local nature reserve. There was a water mill on this site from at least the Norman era. The last mill on the site was built in 1857. Milling continued into the twentieth century, with the last mill buildings eventually being demolished in 1977 and replaced with housing. Further down the river from the mill it is believed there was a Danish camp which was built to protect the Danelaw in 886.

The half-hundred of Weneslawe contained Sandy and 3 additional parishes during the Domesday survey; before Kirby's Quest (1284–86) this half-hundred was merged into the Hundred of Biggleswade. In 1831 the old Weneslawe parishes were listed as Sandy, Sutton, Potton, Hatley, and additionally Everton. A route for a scenic and historic Weneslawe Walk around Sandy, Potton, and Biggleswade was promoted in 2022.

Sandy's parish church of St Swithun was largely rebuilt in 1860, but retaining some of the medieval building, including the tower.

Sandy remained a village into the twentieth century. The central public space is called Market Square, but Sandy was not a market town as such; it was not until 1925 that it was formally given the right to hold a market. Sandy Town Hall was built in 1906 on Bedford Road. This was a large hall built by a private company for public events rather than a being a town hall in the sense of a council's headquarters.

The town expanded rapidly in the 1970s with the development of London overspill housing between Sunderland Road and St Neots Road. This expansion continued into the 1990s with new housing developments at Fallow Field and Ivel Park.

There are two tiers of local government covering Sandy, at parish (town) and unitary authority level: Sandy Town Council and Central Bedfordshire Council. The town council is based at 10 Cambridge Road.

Sandy was an ancient parish. When elected parish and district councils were established in 1894, Sandy was given a parish council and included in the wider Biggleswade Rural District. In 1895 Sandy Parish Council established a council chamber in a room at the fire station at 10 Cambridge Road, which had been built in 1882.

In 1927 the parish of Sandy was made an urban district, making it independent from the Biggleswade Rural District. The urban district council continued to meet at the fire station until 1946, when it bought Boyne House at 7 St Neots Road and converted it to become its offices and meeting place.

Sandy Urban District was abolished in 1974 to become part of Mid Bedfordshire. A successor parish was created covering the former urban district. The re-established parish council declared the parish to be a town, allowing it to take the style "town council" and appoint a mayor. In 1978 the town council left Boyne House and returned to 10 Cambridge Road, this time taking over the whole building; the fire station had moved to a new building on Ivel Road in 1954. Mid Bedfordshire in turn was abolished in 2009 to become part of Central Bedfordshire.

Sandy is within the parliamentary constituency of North Bedfordshire.

Sandy is 43 miles (69 km) north of Central London with the county town of Bedford 8 miles (13 km) to the west. St Neots, Cambridgeshire lies 7 miles (11 km) to the north with Biggleswade 3 miles (4.8 km) to the south.

The River Ivel, a tributary of the River Great Ouse, runs through the town. Parts of the town and adjoining land are designated as a Flood Warning Area. The Greensand Ridge, an escarpment which runs through Buckinghamshire, Bedfordshire, and Cambridgeshire, runs to the south and east of the town.

The Sandy Heath transmitting station, a 244 metre tall television broadcast mast, is located to the east of the town.

Sandy is situated on the A1 which hugs the western edge of the town. The A603 leads west towards Bedford; the B1042 leads east towards Potton and Cambridge.

The original route of the A1 did not go through the centre of Sandy, but passed through the Girtford area on the west side of the town, crossing the Ivel at Girtford Bridge. The A1 bypass was one of the earlier 1950s improvements on the Great North Road. The bypass required a new bridge over the River Ivel, built by Dorman Long. The roundabout (former traffic lights before the late 1970s) is with the A603 for Bedford, to the west and the B1042 into Sandy itself and on to Potton and Cambridge. The former A603, to the east is now the B1042. The former north–south route through the town was over Girtford Bridge, to the west of the current route, and now the A603. There were three separate bypass schemes – the Improvement from Sandy to the junction with A428 (Tempsford and Tempsford Bridge Diversions, began December 1957, finished around 1960), Provision of second carriageway (widening) through Girtford (began 2 January 1961, finished around October 1962), and Biggleswade by-pass to Girtford (Girtford Diversion, which opened on 6 August 1961 which included pulverised fuel ash as an embankment infill material). The Girtford Underpass was built in the early 1990s by Kimbell Construction, at the former Varsity Line railway bridge.

South of the Sandy roundabout the A1 still follows its historic route through the hamlets of Beeston and Seddington, which are in the parish of Sandy. Proposals have been put forward at various times for a bypass, but none have come to fruition.

Sandy has been twinned with the town of Malaunay in France since 1982, as a result of which the Sandy Twinning Association was also established. The association has also recently developed links with the town of Skarszewy in Poland.

Frederick Thomas Bidlake is commemorated by a garden and monument, at Girtford Bridge. It was unveiled on 23 September 1934 as more than 4,000 watched W. P. Cook, president of the Anfield Bicycle Club and the Road Records Association, perform the unveiling ceremony. The rector of Sandy blessed the memorial. The garden is triangular with a wall of local stone on one side. In its centre, a stone reads: "This garden is dedicated to Frederick Thomas Bidlake, a great cyclist, a man of singular charm and character, an untiring worker for cyclists 1867–1933". A sundial in the centre of the garden is marked "He measured time". A facsimile milestone is engraved "F. T. B. Few have known this road as he. London 48 – York 148".

Girtford Bridge itself was built in 1780–82 to the designs of the Rutland architect John Wing (1728–1794) assisted by his son John Wing (1756–1826)

There is a statue of Victoria Cross recipient William Peel in the south transept of St Swithun's Church. Opposite the church across the High Street stands the Sir William Peel pub.
