Denis D'Amour, Canadian guitarist and songwriter (b. 1960)
Denis "Piggy" D'Amour (September 24, 1959 – August 26, 2005) was a Canadian guitarist. D'Amour was a member of the Canadian heavy metal band Voivod from its inception in 1982 until his death from colon cancer in 2005, aged 45.

D'Amour's approach to music was anarchic and experimental rather than strict and theoretical. He was trained in classical violin as a child. He was influenced by progressive rock artists such as King Crimson, Pink Floyd and Rush.
