The Centre for Breton and Celtic Research (CRBC, UR 4451 UBO/UAR 3554 CNRS-UBO) is a multi-disciplinary research laboratory. There are 34 lecturer-researchers (historians in antiquity to the present day, linguists, Celticists and Anglicists, ethnologists, sociologists, literary scholars) working on research themes and fields in Breton and Celtic cultural areas. They also conduct individual or collective comparative research in other fields, mainly at the Atlantic European level and also internationally. The CRBC was founded in 1969 by Yves Le Gallo. 

The 2022–2026 five-year programme focuses on three research areas, a cross-disciplinary centre and a seminar.

CRBC also has 9 research support staff, 31 doctoral students and about a hundred emeritus and associate professors.
