Raffig Tullou (born Raphaël Tullou), alias Neven Lewarc’h (6 January 1909, Mordelles - 16 January 1990 in Saint-Herblain) was a Breton sculptor and set designer. His works included modern Celto-Breton furnishing art, wood carvings, stone carvings, and restoration of historical buildings.
Tullou came to prominence as a member of the Breton artistic movement Seiz Breur, and attempted to adapt his style to merge classical and Breton regional traditions.
Like other members of the group, he was also involved in Breton nationalist politics. Following the split in the Breton Autonomist Party, in 1934, Tullou, Gestalen, Francis Bayer du Kern, Goulven Mazéas and Morvan Marchal created the Breton Federalist Movement, which sought Breton federal autonomy within France. This was set up because of the creation of the extremist Breton National Party, which had pro-Nazi sympathies. Nevertheless, during World War II, he reported for L'Heure Bretonne, the newspaper of the BNP.
In the 1930s Tullou turned his attention towards druidic studies. In 1936, he, Morvan Marchal, and Francis Bayer du Kern founded Kredenn Geltiek Hollvedel (Worldwide Celtic Beliefs), also known as Kevanvod Tud Donn and Dêua Ana. In addition, he also founded a journal about druidic studies and philosophy called Kad (combat). During World War II, the journal changed its name to become Nemeton (sanctuary). Today, it is known as Ialon-Kad-Nemeton.
In 1954, he founded Koun Breizh (Remember Bretons), to promote Breton artistic heritage and Breton administrative organizations. Through the movement he sought to commemorate Breton national heroes, and was responsible for the statue of Nominoë, the first independent Duke of Brittany, at Bains-sur-Oust. He also designed the commemorative plaque for the 18th century Breton rebel Marquis de Pontcallec in the Place du Bouffay, in Nantes.
In 1966, he created Skoed (The Shield) to be the official newspaper of Koun Breizh.
