Glan Afan Comprehensive School (Welsh: Ysgol Gyfun Glan Afan) was a mixed comprehensive school which served the town of Port Talbot, Wales, and its surrounding areas for 120 years. It was opened in 1896 as Port Talbot Intermediate School under the provisions of the Welsh Intermediate Education Act 1889. The school closed in July 2016 to facilitate the merger of Glan Afan itself, Cwrt Sart Comprehensive, Sandfields Comprehensive and Traethmelyn Primary School into the ultra-modern £40millon 'super-school', Ysgol Bae Baglan.

The school was founded in 1896 as Port Talbot Intermediate School and later named the Port Talbot County School. The grammar school took the name Glan Afan in 1951 and in 1959 became Glan Afan Grammar Technical School. In 1965 following the introduction of comprehensive education in Port Talbot the school undertook a further name change, and merged with Velindre Secondary Modern School to become Glan Afan Comprehensive School, taking pupils up to the age of 18. At that time the school's name was written as "Glanafan" rather than "Glan Afan". The school operated from the sites of both the old Grammar and Secondary Modern schools (about a mile apart) and children were regularly bussed between sites during the school day.

The sixth form was moved to Afan College after 1986.

From 1974 to 1996, it was administered by West Glamorgan County Council. In 1996, the Neath Port Talbot County Borough Council was formed, and the school is currently administered by Neath Port Talbot's LEA.

In 2011, Neath Port Talbot LEA announced that Glan Afan School and three other schools will be closed to facilitate a new 'Super' Comprehensive and Primary School. The school was given the name 'Ysgol Bae Baglan' or 'Baglan Bay School' as the name suggests is situated in Baglan Bay on Western Avenue. The facility is now completed and in full function with all pupils from the 4 merging schools transferring to the new site.

Until its closure, the school delivered the National Curriculum at Key Stage 3, (years 7, 8 and 9), and Key Stage 4 (Years 10 and 11).

The curriculum is organised in order to give a broad and balanced experience meeting the needs of all pupils including those with additional learning needs. All pupils have the opportunity to study Welsh culture within individual subjects. The school also organises an annual Eisteddfod and participates successfully at Local and National Urdd Eisteddfoda.

At Key Stage 3, pupils study English, mathematics and science (the core subjects). It also includes these foundation subjects: history, geography, RE, French, Welsh, art, music, technology, ICT, games, PSE and PE. Drama is offered as part of the skills module. In years 7 and 8 pupils have the opportunity to obtain the Key Skills qualifications of Communication, Application of Number and Working with Others at Level 1.

At Key Stage 4, pupils follow a compulsory curriculum of English, mathematics, science, games, RE, Welsh, PSE and ICT (Short Course). They then choose from a variety of subjects organised into option groups. They can choose from GCSE, Vocational GCSE and BTEC vocational courses which are linked with Neath Port Talbot College or other providers.

At Key Stage 4, the school actively monitors and targets pupils to identify underachievement and provides Learning Coach support and mentoring to help pupils with their GCSE studies.

All Year 10 and 11 pupils follow a Personal and Social Education Course, and a programme of Careers Guidance. During year 10 they participate in a week of work experience.

The school ran several clubs, either during lunchtime or after school, including clubs for sports, such as football, hockey, gymnastics, tag rugby, basketball, netball and dodgeball; and curriculum-based clubs including Club Urdd, Computer Club, English ‘Shooting Stars’, Choir, Eco-committee and Art Club.

The school also ran a community group called Glan Afan Silver Surfers for senior citizens from the local community every Monday from 3:30-5pm. The Silver Surfers have been recognised by the High Sheriff of West Glamorgan and the Wales Volunteer of the Year Awards.

Clubs offered in music and drama included Junior Choir, Senior Choir, Guitar Club, Orchestra and Samba Band. The school orchestra made a tour to Belgium. The creative arts departments also put on a full school musical every year, which pupils are encouraged to take part in, and a drama club.
