Loïc Gwenc'hlan Le Scouëzec (11 November 1929, Plouescat, Finistère – 6 February 2008[1]) was a Breton medical doctor, writer, and Grand Druid of Brittany.

After his military service ended in 1958, he became a professor at the French Institute of Athens, as well as in Saint-Didier-en-Velay in Versailles.

He also initiated Skoazell Vreizh, the Breton emergency service, together with Xavier Grall and Yann Choucq in the 1970s.

He wrote the preface in Morvan Lebesque's book Comment peut-on être Breton?

The association Goursez Vreizh (Gorsedd of Brittany), also known as "Breudeuriezh Drouized, Barzhed hag Ovizion Breizh" in Breton or "Fraternité des druides, bardes et ovates de Bretagne" in French (Fraternity of the Druids, Bards and Ovates of Brittany), represents neo-druidism most regularly.
