The gwyniad (Coregonus pennantii) is a freshwater whitefish native to Bala Lake (or Llyn Tegid) in northern Wales.

The population is threatened by deteriorating water quality and by the ruffe, a fish introduced to the lake in the 1980s and now eating the eggs and fry of gwyniad. As a conservation measure, eggs of gwyniad have been transferred to Llyn Arenig Fawr, another nearby lake.^[1][2]

In Britain the gwyniad is usually considered a population belonging to the widespread Eurasian common whitefish (Coregonus lavaretus).^[3] By FishBase and by IUCN, it is listed as a distinct species of the Coregonus genus, C. pennantii.^[1][4]
