Trinity University College (Welsh: Coleg Prifysgol y Drindod) was a Church University College in Carmarthen, Wales.

The institution was founded in 1848 as the South Wales and Monmouthshire Training College, a teacher-training college. It changed its name in 1931 to Trinity College, Carmarthen; and in 2009 to Trinity University College. In 2010, it merged with the University of Wales, Lampeter to become the new University of Wales Trinity Saint David, with the Trinity site becoming the UWTSD Carmarthen Campus.

Trinity University College began life in 1848 as the South Wales and Monmouthshire Training College, making it the oldest teacher training college in continuous operation in Wales. The college's role was to train young men for teaching in Church primary schools. In the first year of operation, 22 students were recruited and were taught by three members of staff including the first Principal, William Reed. Walter Powell is recorded as the first student; he was 17, previously a draper and worked in a grocery store. The college required its students to follow a strict schedule which included getting up at half past six for a cold bath. Students were often recruited from humble backgrounds, and to remind them of this, the college curriculum included subjects such as gardening and woodwork. The students were expected to have a knowledge of grammar and arithmetic and received education in Latin and Greek. By 1936, the college also had an art block and a gym. The college also placed restrictions on interaction with the local townspeople, particularly women, and fines were issued for "girling" (interacting with local women). The strict regime of college life was however broken for activities such as smoking and reading newspapers in the common rooms, musical concerts and entertainment. In the late Victorian era, photography became a great hobby at the college. In the inter-war and post-war era, the college gained a strong reputation for sports. The principal sport played was rugby, in which many students went on to achieve considerable success; but other sports included badminton, tennis, and hockey.

An account of college life in the 1930s is provided by ex-student George Head, who wrote that the Old Building and the Dewi Hostel combined contained all of the teaching rooms, a gymnasium, the library, the smoking room and common rooms, the secretarial offices, and the "Sick Ward" and medical facilities.^{[citation needed]} Church was still at this period a large part of the college life. Interaction with women was still forbidden and punishable. Head does however speak of how fond the students were of the college and how much they took away from it. In particular he recounts the old Trinity College Anthem titled "There is a tavern in the town".

During the Second World War many students were expected to take "fire watches" and serve as lookouts at night, although this job came with little danger in a town like Carmarthen. Many of the students at the college also joined the Home Guard and took part in drills. In 1938 a Broadcast room was constructed, the foundation stone being laid by the Duke of Kent.

In 1931, the college changed its name to Trinity College, Carmarthen. Female students were first admitted in 1957. In 2009, the college achieved "university college" status, and changed its name to Trinity University College.

Trinity College is situated on the outskirts of Carmarthen. It is in a semi-rural setting, surrounded by fields and hills, but is within 10 minutes walk of the town centre. The university is situated around the original Old College of 1848 and is a mixture of lawns and gardens surrounding modern buildings. The main bulk of the university lies along College Road and Job's Well Road, with some buildings situated away from the main grounds. On the outskirts of the town, near the town leisure centre there is the university's outdoor weather pitch. These facilities were inherited by the new university and continue in use today.

• Archbishop Noakes Hall: this was a large accommodation facility that was split into three sections. It could house hundreds of students and was reserved for returning students. The Blocks were all self catered, each room is en-suite, and are divided into flats of eight with one kitchen per flat.
• Myrddin Hall: this was a catered first year hall, built in the late 1960s to accommodate growing numbers of students. The Halls had shared common room space and shared bathrooms.
• Non Hall: originally built in 1957 opposite the old Dewi Hostel to accommodate the first female students. The building had similar facilities to the Myrddin Halls. It remained a single-sex, female block up until the merger, and was reserved for first year catered students.
• Tower Hall: this too was a first year catered block. It was 10 storeys tall and could accommodate many students.
• Picton Hall: Situated on Picton Terrace by the junction with Picton Place, this was used during the 1990s as accommodation for male and female students. It comprised three Georgian houses, two of which were joined via a door on the top-floor. Each house was single-sex. The both co-joined houses housed either all-male or all-female students. Picton residents had their own kitchens but could choose to eat their meals on campus in the canteen. During the late 1990s the hall was unsupervised by a warden and was in poor repair. The buildings are no longer part of the university.

The college could accommodate 600 of its students, though many elected to live in private accommodation in town.

Trinity had a long history of sport and from its very beginnings sport played an important role in students' life. Rugby was an important and strong tradition at Trinity and many of its alumni went on to become very successful in the sport.

The campus' general workshop and costume workshops were used by students of theatre design. Venues for theatrical performances included a tiered theatre in the Halliwell Centre, a 160-seat facility with a sprung floor which could be used for dance rehearsals, Theatr Parry, and Theatr Fach (which contained a green screen and was used as a recording studio).

The college housed workshops designed for different arts and crafts such as woodwork, fine art and ceramics. There were also modern media suites which allowed students to engage with 2D and 3D moving artwork and an Apple Mac lab equipped with dual core i-Macs, as well as Mac Pro towers to enable students to have an industry standard experience. In addition, the campus was home to the "final cut" film studio and recording and editing studios used by Film and Media students.

Historically, Trinity College was primarily concerned with the discipline of teacher training. It had a long and constant history with the subject. This tradition continued throughout the institution's history and the college became one of the UK's chief providers of the subject.^{[citation needed]} As it developed, Trinity College began to teach a wide range of subjects including:

• Business and Tourism
• IT, Computer and Internet technology
• Health Science, Nutritional science, and Sports Science
• Social Inclusion and Justice
