Ysgol Dinas Brân is an 11-18 bilingual co-educational secondary school in Llangollen, Denbighshire, Wales. It serves the town of Llangollen and the surrounding areas including Corwen, Wrexham, Johnstown, Ruabon, Cefn Mawr, and Trevor.[2] The school was previously called Llangollen Grammar School.[3] [4] The school had 1072 pupils on roll in 2023.[5]
In the January 2012 National ranking of all secondary schools in Wales, the school was listed 7th (out of 230 school) - making Ysgol Dinas Brân the 3rd best school in North Wales.[6]
In 2018, only 2% of students speak Welsh as a first language or to an equivalent standard, with approximately a tenth of pupils being educated in the Welsh-medium stream of the school.
The school motto is Success through Effort.
In 2008 the school opened its new Sixth form and learning centre on the campus. The sports hall was opened in 2000.

Each year, the International Musical Eisteddfod starts every first week of July, and Ysgol Dinas Brân holds a transition week, where all of the Year 6 students are introduced to their soon-to-be Secondary School. Ysgol Dinas Brân holds a session for the Year 6 students and the pupils of Ysgol Dinas Brân, where they go to the International Eisteddfod and visit the stalls and the Llangollen Pavilion for an hour at the school.
The school buildings were constructed in the 1930s and added to on an ad-hoc basis.[1]
