Otello Bignami (August 6, 1914 – December 1, 1989) was an Italian violin maker from Bologna.
The life of Otello Bignami closely resembles the lives of various 19th-century violin makers in that he drew much vitality from the farming and craft traditions of his origins.
In 1976 he was awarded a "gold violin" from the city of Bagnacavallo; subsequently he won a prize for his special dedication to teaching.
In the course of over forty years of incessant activity, he built a vast number of instruments in the violin family, including several quartets.
He painted landscapes, still life, and flowers with sweet and melancholic shades, usually giving them away to relations and friends.
