Wellington School is a co-educational fee-charging boarding and day school in the English public school tradition for pupils aged 3–18 located in Wellington, Somerset, England. Wellington School was founded in 1837.

Wellington School is a registered charity and has around 800 pupils currently in attendance. Around 150 of those pupils are boarders. The school is a member of the Headmasters' and Headmistresses' Conference. Wellington School is based on a 35-acre campus in Wellington, Somerset.

Wellington School operates its own feeder preparatory school, Wellington Prep School which shares the main campus. Wellington Prep School students often use the sporting pitches and science labs of Wellington School.

Wellington School is situated to the south of the centre of the small town of Wellington. It was founded originally as Wellington Academy in 1837 as an all-boys school by Benjamin Frost (Headmaster 1837–1848). It was later purchased and run by Frost's wife and William Corner (Headmaster 1848–1879). In 1879 under new headmaster Francis Raban renamed the school West Somerset County School, although only 34 years later the school was again renamed but this time as Wellington School, the name it retains today.

The school was originally founded as a private boys' school, but in the early 1970s girls were first accepted into the Sixth Form. From 1979 girls were accepted from the age of 10.

The school opened a new junior school in 2000, having previously only catered for pupils aged 10 and over. This was renamed "Wellington Prep School" in 2015.

In 2003 the Princess Royal opened the Princess Royal Sports Complex, a £2.65 million indoor sports facility. The Princess Royal Sports Complex was offered to competitors in the 2012 London Olympics for training.

The Good Schools Guide described Wellington School as "Friendly, purposeful and busy, it is a solid, well-managed school, neat but not glossy, giving its pupils a sound education and masses of high points in developmental experience." The Guide also described Wellington School as "Down to earth. Punches above its weight. No sense of entitlement. Good value for money. Not our words, those of a parent. Says it for us, too".

Coat of arms of Wellington School, Somerset

Notes Granted 2 November 1926 The open book represents learning. The dragons represent the county of Somerset. In the centre of the chief (upper part of the arms), there is a 'quarter' from the arms of the Duke of Wellington Escutcheon "Sable, an open book proper, edged and clasped Or and inscribed with the words 'Nisi Dominus frustra'; on a chief Or, between two dragons rampant combatant, a pale gules charged with a cross argent, in each canton five plates in saltire" Motto Nisi Dominus Frustra (Without the Lord, our efforts are in vain)

The school has rugby pitches, cricket squares, football pitches, an all-weather pitch, all-weather training areas, tennis courts, squash courts, climbing wall and an indoor swimming pool.

Football was reintroduced in the 2003 school year.

Many students have gone on to represent the school in county and England hockey, national athletics, county and England fencing and county rugby.

The school's music department, dedicated to the ex-headmaster George Corner, includes a recording studio, iMac suite, and percussion studio as well as many practice rooms and two classrooms. All 15 pianos in the department are by Steinway & Sons, accrediting the school as an 'All Steinway School', the first of its kind in England.

Regular concerts are held throughout the school year, performance spaces include the department's 'Small Hall', the school's main hall (Great Hall) and the school chapel which is fitted with an electronic organ alongside a Steinway baby grand.

Built between 1928 and 1931 by C. H. Biddulph-Pinchard, the Grade II listed red brick building is dressed with stone and has a flat roof which is concealed behind a parapet. It is a rectangular single-cell chapel with a carved stone altar. The Chapel went through specialist restoration work in 2013 which involved the repainting of the ceiling among other maintenance tasks. This restoration was funded partly by the school's Old Wellingtonians' Association

The east end of the building holds choir stalls and an organ loft over the entrance vestibule. The interior is highly decorated with finely carved wooden wall panels and elaborately decorated canopies made of molded plaster.

The Church of England Chapel has a full-time Chaplain who prepares pupils for Confirmation annually. Though some assemblies and concerts are also held in the building, there are Sunday services throughout term time for boarders and members of the public; these involve regular performances by the school's chapel choir. There are also shorter services most days during the week with pupils attending on a house rota basis.

The Chapel was built as a memorial to those who fell during the first world war. George Corner, the then headmaster, wrote to the Old Boys and asked for their support in the project. The 37 members of the Wellington School Community who gave their lives are listed on the walls of the Chapel. Each year a pupil from each boarding house remembers one former pupil specifically, researching how and where they died and a basket of flowers is laid in their memory.

Confirmation and all the other occasional offices of the church are open to all members of the school community on request.

The school has a marching band and active Combined Cadet Force, founded in 1901. The Combined Cadet Force is open to senior school pupils, and has upwards of 170 cadets across the Royal Navy, Army and Air Force sections.

The cadets learn military based skills such as drill, weapons handling, map and compass, battlecraft, climbing, abseiling and leadership development. There are various CCF camps, military training weekends and cadet competitions each year, during which the cadets go on field manoeuvres in order to apply the skills they have learned in a practical situation.

Wellington School is unique in having three field exercises a year, each lasting three days and two nights. A full-time member of staff at Wellington School runs the CCF and acts as the senior officer. He is assisted by an experienced warrant officer. The cadets are required to present themselves for inspection by the masters in charge of each section on a weekly basis.
