Dom Michel Le Nobletz (Breton: Mikel an Nobletz) (1577–1652) was a vigorous Counter-Reformation missionary active in the west of Brittany, who was responsible for a revival of popular Catholic culture. He developed new methods of teaching, and invented distinctive painted placards — known as taolennoù – which became widely used in the area.

His extremely severe views and denunciations of alleged vice among local business leaders and even other priests led to accusations that he was a fanatic; he was nicknamed "the mad priest". He was forced to leave Douarnenez because of the animosity he engendered.

The Church declared Nobletz "venerable" in 1897. The Bishop of Leon initiated his beatification in 1701, but it is still pending.
