The origin of Boston Spa's name is not entirely clear; the name is not attested prior to appearing on printed maps in 1771, when it was labelled Thorp Spaw. At this stage, then, the name Thorp Spaw presumably meant 'the spa associated with Thorp Arch'. The Bostonelement of the name is first attested in 1799 as Bostongate and then in 1822 simply as Boston. It is thought probable that Boston was the surname of a local family, whose name itself derives from Boston, Lincolnshire, and that their name was given to the settlement that grew up around the spa.
History
In 1744, John Shires established a spa town when he discovered sulphur springs in the magnesian limestone. It was known as Thorp Spa but declined when Harrogate became very popular as a spa town. In 1753, a turnpike was built on the Tadcaster to Otley road, which passes through Boston Spa. In the same year, Joseph Taite built a house to accommodate visitors that became the Royal Hotel, which is still standing, but converted into flats and shops. By 1819, Boston Spa had a population of more than 600, and several inns and other houses offering accommodation had been built. Spa baths were built to allow visitors to take the waters. On the north bank of the river is the village of Thorp Arch, which predates Boston Spa by several centuries. The Boston Spa and Thorp Arch Conservation Area, designated in 1969, extended across both Boston Spa and Thorp Arch parishes. It was revised in 2009, restricting the boundaries to Boston Spa parish and reshaped to exclude areas of late-20th-century estate housing to the south of the High Street. The current conservation area boundary focuses on the historic settlement. It was extended to the west, to encompass West End, an area of dwellings constructed during the Second World War to house workers from Thorp Arch munitions factory. The war had a major effect on Boston Spa's population, society and surroundings, and the buildings stand as a testament to that history.
Boston Spa has a post office, a small library and a filling station. There are two public houses,, a small Costcutter supermarket in the former Royal Hotel and several independent retailers in the village centre. The Crown Hotel closed in 2012 and was subject to a public enquiry as to its future use. Arguments presented in 2014 by Tesco that the premises "had little or no use as a hotel facility" were accepted at appeal. The Boston Spa branch of the British Library is 1.5 miles north-east of the village and outside the civil parish. This branch contains almost the complete British Library newspaper collection. There are two churches St Mary's Anglican Church and Boston Spa Methodist Church.

There are three primary schools in the village: Primrose Lane Primary School, St Edward's Catholic Primary School and St Mary's CE Primary School.

The school has success in sports and scienceteaching, and caters for pupils undertaking GCSEs, A levels, GNVQs and those with special needs according to its Ofsted reports. Other educational establishments with postal addresses of Boston Spa although sited in the nearby parish of Clifford include the children's hospice Martin House and St John's Catholic School for the Deaf which has a UK-wide catchment.
